    The research and implementation of portable and low-cost analytical devices that possess high reproducibility and ease of operation is still a challenging task, and a growing field of importance, within the analytical research. Herein, we report the concept, design and optimization of a microfluidic device based on electrochemiluminescence (ECL) detection that can be potentially operated without electricity for analytical purposes. The device functions exploiting the concept of streaming potential-driven bipolar electrochemistry, where a potential difference, generated from the flow of an electrolyte through a microchannel under the influence of a pressure gradient, is the driving force for redox reactions. To our purpose, we employ such a device to drive the ECL reaction of an organic chromophore deposited onto the electrode surface by simply flowing an electrolytic solution containing a coreactant into the microfluidic system, and we successively apply such device for the detection of amines in water. Our device shows high reproducibility and satisfactory detection limits for tri-n-propylamine, demonstrating an original, and up to now unexplored, concept of energy saving microfluidic systems with integrated ECL detection.

  2. Co-continuous hard Carbon/NASICON electrodes for all-solid-state batteries: Insights into structural stability and interfacial Na-ion transfer 査読有り Open Access

    Sodium-ion batteries (SIBs) have recently been launched as alternatives to lithium-ion batteries (LIBs). Since the superiority of SIBs over LIBs lies in the abundance and low cost of raw materials, SIBs are expected to be deployed in large-scale storage systems, where long-term stable operation with a high level of safety is demanded rather than high energy density. On this account, all-solid-state sodium-ion batteries (ASS-SIBs) comprising an air-stable oxide solid electrolyte are of great promise but still in their infancy. In this study, we focus on hard carbon, which is first in line for SIB anodes, in conjunction with a NASICON-type solid electrolyte, Na<inf>3</inf>Zr<inf>2</inf>Si<inf>2</inf>PO<inf>12</inf> (NZSP), and elucidate the underlying electrode capability of hard carbon for ASS-SIBs. Monolithic NZSP/carbon electrode layers with an elaborately designed co-continuous microstructure have been fabricated via the sol–gel technique to exploit the potential of hard carbon. Consequently, the favorable performance of hard carbon in the NZSP-based ASS cell is validated: a reversible capacity of >300 mAh g<sup>–1</sup>, an initial coulombic efficiency of 94 %, and a stable cycling over 500 cycles. The striking longevity underpins a minuscule volume change of carbon during sodiation/desodiation. The kinetic study on the interfacial Na<sup>+</sup>-transfer highlights the lower activation energy (∼0.4 eV) at NZSP/carbon interface than that in a liquid electrolyte. All the findings in this study clearly corroborate the significant potential in the combination of hard carbon anodes and NASICON-type solid electrolytes for ASS-SIBs.

    Two Dion–Jacobson (DJ) double-layered perovskites CsNdNb<inf>2</inf>O<inf>7</inf> and RbNdNb<inf>2</inf>O<inf>7</inf> exhibit hybrid improper ferroelectricity, in which spontaneous polarization is induced by coupling of two types of nonpolar oxygen octahedral rotations (OORs). Their crystal structures adopt common polar distortion modes, although they exhibit distinct OOR patterns. In this study, complete solid-solution Cs<inf>1-x</inf>Rb<inf>x</inf>-NdNb<inf>2</inf>O<inf>7</inf> ceramics (x = 0, 0.25, 0.5, 0.75, and 1) have been synthesized by conventional solid-state reaction methods, and the temperature-composition phase diagram has been established by various methods including variable-temperature synchrotron X-ray diffractometry, differential scanning calorimetry, optical second harmonic generation, and dielectric permittivity measurements. The powder X-ray diffractometry reveals that Cs-rich compounds (x r 0.25) crystalize into polar P2<inf>1</inf>am structures with a<sup>-</sup>a<sup>-</sup>c<sup>+</sup>/a<sup>-</sup>a<sup>-</sup>c<sup>+</sup> OORs at room temperature, while Rb-rich compounds (x Z 0.5) adopt polar I2cm structures with a<sup>-</sup>a<sup>-</sup>c<sup>+</sup>/-(a<sup>-</sup>a<sup>-</sup>c<sup>+</sup>) OORs. All the solid solutions exhibit ferroelectricity at room temperature. Upon heating, successive phase transitions involving the loss of polar distortions and OORs have been observed. The phase transition temperatures of the solid solutions with intermediate compositions are lower than those predicted based on Vegard’s law, indicating structural frustration effects due to the random arrangement of two alkali metal ions. This work provides insight into the influence of alkali metal ions in the intervening layers on the structural and ferroelectric properties of DJ layered perovskites.

    The urgent global transition away from fossil fuels, driven by climate change mitigation, rising energy demands, and exponential growth of high-energy-consuming AI technology, calls for every available sustainable renewable energy solution. DSSCs emerge as promising photovoltaics due to their cost-effectiveness, efficiency in low-light conditions, versatility, and aesthetic appeal. A crucial avenue for enhancing DSSC sustainability lies in utilizing natural dyes as sensitizers. This study explores novel natural dye extracts from the pod husk of Parkia biglobosa, employing seven different solvents to investigate their photovoltaic potential. Some extracts exhibit exceptional light absorbance with band gaps ranging 1.82-2.85 eV—comparable to the high-performing synthetic N719 dye (1.75 eV). These performances surpass typical natural dyes with band gaps ≥2.0 eV. Photovoltaic performance assessments yielded efficiencies between 0.07-0.19%, within the reported range of natural dye DSSCs (0.05-4.2%; usually of high purity or combinations), though significantly lower than N719 (6.22%). Photoanode thickness reduction from 8 to 5 μm enhanced efficiencies to 0.09-0.24% (compared to 4.20% for N719), yet fell below anticipated values based on strong optical absorption. Subsequent characterizations—TG-DTA, IPCE, PL, EIS, FT-IR, and CV—identified two primary limiting factors: high series and ion diffusion resistances, attributed to inefficient band alignments with TiO<inf>2</inf> and the I<inf>3</inf><sup>−</sup>/I<sup>−</sup> electrolyte, and dye degradation. Optimizing DSSC architecture through appropriate semiconductor materials and redox electrolytes could significantly improve these natural dyes performances. This work advances the potential for cost-effective, eco-friendly, high-performance DSSCs and contributes to groundwork for future advancements in sustainable solar energy.

    Oxide-based all-solid-state sodium-ion batteries present a safer, more robust and more sustainable alternative to lithium-ion batteries, though fabrication challenges persist, particularly during co-sintering. In this study, we demonstrate that by adding sodium borate-based sintering aids to highly conductive Na<inf>3</inf>Zr<inf>2</inf>(SiO<inf>4</inf>)<inf>2</inf>(PO<inf>4</inf>) (NZSP)-based materials, both a lower sintering temperature and high ionic conductivity can be achieved. Specifically, the mixture of Na<inf>2</inf>CO<inf>3</inf> and B<inf>2</inf>O<inf>3</inf> as a sintering aid is crucial, and samples sintered at 900 °C with a Na<inf>3.4</inf>Zr<inf>1.95</inf>Al<inf>0.05</inf>(SiO<inf>4</inf>)<inf>2.35</inf>(PO<inf>4</inf>)<inf>0.65</inf> composition exhibits a Na<sup>+</sup> ion conductivity exceeding 4 × 10<sup>−3</sup> S cm<sup>−1</sup> at room temperature. These materials are also compatible with co-sintering alongside hard carbon anode materials. The all-solid-state cell, featuring a composite electrode of spherical hard carbon particles and optimized NZSP-based electrolytes, demonstrated stable charge-discharge performance at room temperature, retaining a capacity of 140-220 mA h g<sup>−1</sup> across 80 cycles.

    Calcium copper titanate (CCTO) is a novel functional material renowned for its exceptional dielectric properties and recent application as a photocatalyst. This study employs a green aqueous facile sol-gel technique to synthesize template-free, 3D-connected hierarchically porous monolithic CCTOs under two gelation and aging conditions (30 °C and 40 °C). Both samples exhibited identical thermal, crystalline, compositional, optical, and bandgap characteristics, with intrinsic direct and indirect band gaps of 1.99 eV and 1.71 eV, respectively. However, the porosity differed: the 30 °C sample had a higher macropore volume, while the 40 °C sample had a higher meso-/micropore volume, resulting in BET surface areas of 127 m²/g and 53 m²/g, respectively. Despite high calcination at 1100 °C (> 100 nm particle size), which reduced surface areas to 0.4 m²/g and 0.5 m²/g, the pore structures remained. These one-step, template-free hierarchically porous CCTO materials show significant potential in catalysis, offering advantages such as efficient mass transport within macropores, high active surface area within meso-/micropores, reduced diffusional limitations, improved catalyst recovery due to their monolithic morphology, and visible region light absorbance for photocatalysis. The research shows the mesopore/surface area can be improved via lower-temperature calcination (e.g. 800 °C; 40 nm particle size) with extended duration, or alternative techniques like microwave calcination.

    Bipolar electrode (BPE) systems have been attracting increasing attention owing to their cost-effectiveness and wireless design. Recently, the concept of streaming potential-driven BPEs for the oxidative electropolymerization of aromatic monomers without the need for an electric power supply is reported. However, the previous system, which used cotton as a filler material, had limitations in inducing suitable potential differences and charge amounts. Herein, various electrolytes and filling materials for flow cells are investigated for generating streaming potential. The results demonstrate that the use of bicontinuous porous filler materials and electrolytes containing ammonium cations and small anions effectively induces high streaming potential values. Consequently, the monomer scope of the electropolymerization method is extended compared to that of the prototype cell. In addition, a divided flow cell is developed to overcome the limitations of the available reaction.

    Streaming potential is the potential difference established between the inlet and outlet of a narrow channel while pumping a low-concentration electrolyte and is used in various applications, such as power generation devices, zeta potential analyzers, and electrochemical reactions. However, the effects of cell parameters, such as the geometry and resistance of channels with porous fillers, on streaming potential generation have not been clarified. Herein, the effects of the shape of a channel filled with a porous phenolic resin monolith material on streaming potential and current generation behavior were comprehensively investigated. Additionally, the energy conversion efficiency of streaming potential generation using a cell based on this channel was elucidated.

    Improvement of mechanical stability for porous polymer monoliths is one of the prime concerns as represented by the long-standing research efforts on resorcinol-formaldehyde (RF) aerogels. To this end, it is imperative not only to tailor mechanically robust porous morphology but also to design macromolecular structure of polymer scaffolds. Previously, we have developed porous RF gels showing a unique mechanical feature combining high mechanical strength and outstanding flexibility against uniaxial compression. Comparison of mechanical properties between the porous gels with varied morphologies has elucidated the influence of porous structure, whereas effects of macromolecular structure still remain elusive. Herein, we have fabricated a series of macroporous phenolic resins from three types of linear prepolymers with phenol pendant groups, poly(4-vinylphenol) or poly(4-hydroxystyrene), which differ in molecular-weight properties, by the sol–gel process in conjunction with spinodal decomposition. The difference in gelation and phase separation behaviors observed for the discrete systems indicates the dissimilar cross-linked networks developed in the respective gels, which consequently influence the mechanical strength and flexibility against uniaxial compression. This study also demonstrates the improvement of mechanical features by thermal treatment for the porous monoliths derived from the high-molecular-weight prepolymer with a view to the application in mechanical energy absorption.

    A new synthetic strategy to produce porous ceramic particles with well-defined polyhedral particle morphology and three-dimensionally interconnected mesoporous structure has been developed by means of the combination of topotactic conversion of polyhedral crystal precursors and pyrolysis-induced phase separation. The crystal morphology of precursors is controlled by the liquid-phase synthesis, while the mesoporous structure in each polyhedral particle is tailored by the selective removal of a phase-separated phase preserving the other phase. In this review, two examples of porous polyhedral metal oxides prepared from hydrogarnet precursors: mesoporous and mesocrystalline 12CaO • 7Al<inf>2</inf>O<inf>3</inf> mayenite microcubes and porous SrFeO<inf>3-δ</inf> perovskite polyhedral particles. The synthesis and characterization of these porous materials as well as their applications in catalysis are overviewed.

    Introduction of open mesoporosity into microparticles with a robust morphology provides a high active surface area together with good thermal stability and shows benefit in various applications at high temperatures. Recently, nonstoichiometric Sr-Fe perovskites with an oxygen release/absorption capability have attracted interests as an oxidation catalyst operated at elevated temperatures. Here, we demonstrate the topotactic synthesis approach to fabricate mesoporous microparticles of SrFeO3−δ with monodispersibility as well as rhombic dodecahedral morphology from the correspondent hydrogarnet precursor (Sr3Fe2(OH)12) prepared by the hydrothermal reaction. Relationship between synthetic conditions and the formed crystal morphology has been systematically explored, which discloses that the crystallization of hydrogarnet can take place at as low as 40 °C. On heating, the dehydration of Sr3Fe2(OH)12 gives rise to phase separation into Sr(OH)2 and SrFeO3−δ via a transient phase of “oxyhydrogarnet”. Selective removal of the Sr(OH)2-derived phase leaves three-dimensionally interconnected mesopores in individual polyhedral microparticles. Meanwhile, further increase of the heat-treatment temperature sets off the reaction between the two separated phases, ending up in nonporous polyhedral particles composed of Ruddlesden-Popper-type layered perovskite (Sr3Fe2O7−δ) at 1200 °C. The mesoporous SrFeO3−δ polyhedral microparticles exhibit an enhanced catalytic performance of CO oxidation superior to the nonporous counterparts, which is associated with the stimulated oxygen release capability owing to mesoporosity rather than the oxygen uptake rate.

    Impacts of an electrode active material with 1 μm scale thickness on the performance of an oxide-based all-solid-state battery (ASSB) have been investigated by metallic Na | Na3Zr2(SiO4)2(PO4) (NZSP) | Na3Ti2(PO4)3 (NTP) cells. Dense crystalline NTP layer is formed on NZSP ceramic electrolyte using spin coating of glass powder suspension and subsequent crystallization (glass-ceramic process). A sample with 0.6 μm thick NTP layer exhibits 0.1 C charge/discharge cycling with very small polarization (<0.03 V), and its initial capacity of ∼60 mA h g-1 is retained >80% after 60 cycles. Fast cathode kinetics also realized the 0.1 C capacity at −20 °C to be ∼80% retention. Furthermore, a facile control over the thickness of cathode films without any conductive additives in the 1 μm range demonstrated in this work enables the assessment of cathode kinetics. Electrochemical impedance spectroscopy revealed that Warburg resistance originates from an ambipolar diffusion of an electron and Na+ ion. The methodology presented here paves a way for rapid examinations of electrode material compatibility and electrode design for next-generation oxide-based ASSBs.

    Electrochemical devices that harvest or store electrical energy are indispensable to our daily life and are currently of growing importance in the future prosperity of the world economy. The sol–gel technology has contributed substantially to the development of electrode materials and electrocatalysts, particularly in terms of the synthesis of nano-sized and/or nanostructured particles. As with the other application fields, nanomaterials with enriched active surface sites can enhance electrode performance, and hence, have been substituted for the classical low-surface-area electrodes like rods and plates. However, the powdery nanomaterials need to be fixed on an electrode substrate in a mixture with binders and conductive agents, which imposes several drawbacks especially in fundamental research. In this context, free-standing and binder-free monolithic electrodes bearing rationally designed nanostructures have emerged as advanced electrode materials based on the concept of incorporating the nanomaterials into the classical bulky electrodes. This review focuses on the recent progress in porous monolithic electrodes with special concern for those with three-dimensionally interconnected porous structures prepared via the sol–gel processes accompanied by phase separation. In addition to the synthesis and pore control for various electrode materials, the insights garnered from the electrochemical investigations on the porous monolithic electrodes are overviewed.

    Thermal insulating materials are of importance for efficient and effective use of heat energy. Porous organic foams are widely employed for this purpose owing to their low thermal conductivity and mass productivity at low cost. However, the poor thermal stability of organic polymers limits their availability within a low temperature range (typically, < 150 °C). In this paper, we demonstrate the one-pot sol–gel synthesis of porous poly(amic acid) (PAA) xerogels and their conversion to porous polyimide (PI) monoliths by thermal imidization. The PAA networks crosslinked with either aromatic or aliphatic triamine and the bicontinuous porous morphology tailored via spinodal decomposition allow the evaporative drying at ambient pressure to obtain low-density PAA xerogels without significant shrinkage. The aromatic crosslinker yields the porous PI monoliths with higher porosity and flexible feature as compared with those prepared with the aliphatic triamine. On the other hand, the porous PI monolith based on the aliphatic crosslinker possesses slightly higher thermal stability owing to the stiffer mechanical property. The durability test results verify the porous PI thermal insulators are available in air at up to ~450 °C for a short period and up to ~350 °C for a long term. [Figure not available: see fulltext.]

  17. Glass-ceramic route to NASICON-type Na Ti2(PO4)3 electrodes for Na-ion batteries 査読有り Open Access

    Glass-ceramic processes to prepare NASICON-type NaxTi2(PO4)3, which is an anode candidate for sodium-ion batteries, from 30Na2O–40TiO2–30P2O5 glass have been investigated with varied atmospheric conditions. By annealing in the inert (N2) atmosphere, the glass started crystalizing into NASICON-type NaTi2(PO4)3 with rhombohedral symmetry at ∼600 °C followed by crystallization of other phases to be multiphase mixtures at higher temperatures. In contrast, in the reducing (5% H2/Ar) atmosphere, NASICON-type Na3Ti2(PO4)3 with triclinic symmetry is crystallized at >∼800 °C. The formation of Na3Ti2(PO4)3 is associated with a loss of excess oxygens in the initial glass composition and a reduction of Ti from Ti4+ to Ti3+. The reduction process upon the glass-to-ceramic conversion was traced by in-situ observation during the thermogravimetric analysis. It is also revealed that the electrochemical Na + -storage capabilities of the glass-ceramic electrodes are correlated with the Na-ion occupancy between these two phases, and their phase fractions affect the charge-discharge properties of Na-ion cells. Finer glass-ceramic powders could improve the electrochemical properties and achieve almost 80% of its theoretical capacity.

    Porous nonoxide ceramics have exhibited impressive progress in terms of synthesis and applications over the past few decades because of their unique characteristics distinguished from the oxide counterparts. From the synthetic aspect, the preceramic polymer route, where nonoxide ceramics such as carbides and nitrides are produced from molecular precursors, offers exceptional opportunities to elaborate and control the material shape as well as the micro- and nanostructures in concert with various techniques. This review presents monolithic ceramic materials based on various reduced phases bearing hierarchical porosity with a focus on those obtained from macroporous preceramic monoliths prepared via the one-pot sol–gel process accompanied by spinodal decomposition. Here, we highlight two classes of preceramic inorganic–organic hybrid gels: organometallic crosslinked polymers based on poly(silsesquioxane)s and nonorganometallic hybrid networks related to Ti without Ti–C bonds. The polymer-to-ceramic conversion processes are discussed with concern for the crystal transition behaviors and the variation of pore properties in different length scales upon heating. In addition, although out of the preceramic polymer category, some examples of inorganic–organic nanocomposite gels with a carbonizable polymer and/or urea for yielding porous metal carbides and nitrides in a monolithic form are introduced as well, which provides extended versatility toward a variety of transition metal systems.

    Preceramic polymer routes, which produce ceramic products called polymer-derived ceramics (PDCs) from molecular precursors, have been developed as a powerful tool to synthesize reduced ceramics in different morphologies (fibers, coatings and monoliths) for over half a century. In recent years, pore control of porous ceramic monoliths has attracted attention for improving their functionalities, which has driven the preceramic polymer routes to be integrated with other synthetic techniques for porous materials such as templating, foaming, emulsion and phase separation. This article briefly overviews porous PDC monoliths with a special emphasis on those derived from porous preceramic polymer gels which are prepared via the solgel process accompanied by spinodal decomposition. Ceramization behaviors of Si- and Ti-based preceramic polymers are highlighted in terms of crystal transition and variation of pore properties in different length scales.
