Biomass electrolysis enables hydrogen (H2) production at onset voltages of less than 1 V, depending on the fuel species. However, biofuel derived from biomass not categorized as food and produced from environmentally friendly processes is needed for the development of sustainable strategies. In addition, the biofuel should not require special and expensive procedures for processing. The present report describes the direct electrolysis of waste newspaper for H2 production. Cellulose and lignin included in the newspaper were subject to dissolution and hydrolysis in a phosphoric acid solvent at the anode in a temperature range of 100–175 °C. The resulting decomposition products were electrolyzed to H2 and carbon dioxide (CO2), at low onset voltages (ca. 0.2 V) and high current efficiencies (H2: 1.0, CO2: 0.9). Carbon black functionalized with carbonyl groups showed greater catalytic activity than a Pt/C catalyst for the anode reaction. H2 yield reached ca. 0.2 g per 1 g of newspaper in a batch cell. H2 was produced continuously in a current-density range of 0.15–0.25 A cm−2 while maintaining plateau-like voltage behavior in a flow cell. The energy consumed for electrolysis at a current density of 0.15 A cm−2 was as low as 1.27 kWh (Nm3)−1.

SnSO4 was employed as an anode-active material for rechargeable batteries, where Sn4+ and Sn2+ ions are reduced to Sn2+ and Sn, respectively during charge while the inverse reactions occur during discharge. Undesired hydrogen production was substantially avoided by adjusting the charge voltage to 1.5V. The resulting cell functioned as a battery with an electrical capacity of 258mA hg-1 at 10mA cm-2 and as a fuel cell with power densities of 55-125 mW cm-2 at 0.8V.

There have been many attempts to develop solid-state sensor devices for detecting particulate matter (PM) in diesel exhaust; however, in most of these, the accumulated PM must be burned intermittently to allow subsequent sensing cycles. Here, we report a self-regenerable PM sensor using a proton conductive solid electrolyte and an active working electrode for PM oxidation. The withstanding voltage capability of BaZr0.8Y0.2O3-δ was greatly improved by the growth of a dense Zr1-xYxP2O7 film on the electrolyte surface. The reaction of PM with active oxygen under anodic polarization was further enhanced by the addition of IrO2 to the working electrode. As a result of these combined modifications, when the working electrode was anodically polarized, PM was oxidized to CO2 according to a four-electron reaction (C + 2H2O → CO2 + 4H+ + 4e-) while remaining below the self-ignition temperature. This amperometric sensor successfully produced a current signal corresponding to the quantity of PM in a gas stream at an operating temperature of 300°C. These results demonstrate that the sensor can carry out continuous monitoring of PM concentrations while self-regenerating.

Low-temperature Sintering of Yttria-stabilized Zirconia Using Bismuth-Vanadium Oxide as a Sintering Aid at 800 degrees C Reviewed

Nagao Masahiro, Kobayashi Kazuyo, Hibino Takashi

CHEMISTRY LETTERS Vol. 43 ( 12 ) page： 1887 - 1889 2014.12

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Chemistry Letters

The effect of the addition of copper-doped bismuth-vanadium oxide to yttria-stabilized zirconia (YSZ) on the sinterability and electrical conductivity, especially in reducing atmospheres, has been investigated. When Bi2Cu0.1V0.9O5.35 was used as a sintering aid, the sintering temperature could be reduced to 800°C, whereas the conventional sintering process requires temperatures above 1300°C. Although the conductivity of YSZ with 1.5 mol% Bi2Cu0.1V0.9O5.35 was slightly lower than that of pure YSZ si ntered at 1300°C, no PO2 dependence was observed under reducing conditions (e.g., PO2 = 10-5-10-24 atm), which indicates that the electrolyte is applicable to solid-oxide fuel cells.
