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

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.

[NiFe]Hydrogenase from Citrobacter sp S-77 Surpasses Platinum as an Electrode for H-2 Oxidation Reaction Reviewed

Matsumoto Takahiro, Eguchi Shigenobu, Nakai Hidetaka, Hibino Takashi, Yoon Ki-Seok, Ogo Seiji

ANGEWANDTE CHEMIE-INTERNATIONAL EDITION Vol. 53 ( 34 ) page： 8895 - 8898 2014.8

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Angewandte Chemie - International Edition

Reported herein is an electrode for dihydrogen (H2) oxidation, and it is based on [NiFe]Hydrogenase from Citrobacter sp. S-77 ([NiFe] S77). It has a 637 times higher mass activity than Pt (calculated based on 1 mg of [NiFe]S77 or Pt) at 50 mV in a hydrogen half-cell. The [NiFe]S77 electrode is also stable in air and, unlike Pt, can be recovered 100% after poisoning by carbon monoxide. Following characterization of the [NiFe]S77 electrode, a fuel cell comprising a [NiFe] S77 anode and Pt cathode was constructed and shown to have a a higher power density than that achievable by Pt. © 2014 WILEY-VCH Verlag GmbH & Co.

Mixed Potential Response for Hydrocarbons in a Proton-Conductive Electrochemical Cell Operated at Room Temperature Reviewed

Hibino Takashi, Kobayashi Kazuyo

JOURNAL OF THE ELECTROCHEMICAL SOCIETY Vol. 161 ( 5 ) page： H326 - H331 2014

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Journal of the Electrochemical Society

Themixed potential response for various hydrocarbons at room temperaturewas investigated using proton-conductive Sn0.9In0.1P 2O7 as an electrolyte. Among the tested electrodes, Pt/C exhibited the most negative potential in a feed mixture of 1000 ppm propene, 10% oxygen, and ca. 3% water vapor. The potential of this electrode was further shifted to a more negative value by the addition of Sn0.9In 0.1P2O7 to the electrode. The resultant potential vs. an air electrode reached ?78 mV at 1000 ppm propene, which is a significant deviation from that calculated from the Nernst equation. This non-Nernstian potential also became enhanced as the concentration and carbon number of the hydrocarbon increased, with the C-C linkage unsaturated, and with a branched chain structure. These enhancement effects could be explained by the polarization curves for hydrocarbon and oxygen, where CO2 formation through hydrocarbon oxidation and water vapor formation through oxygen reduction were in competition with each other. It should be emphasized that the heterogeneous catalytic reaction of the hydrocarbon with oxygen did not occur over the electrode, which allowed not only for a simple mixed potential theory, but also for the potential properties to be independent of the supply gas flow rate. © 2014 The Electrochemical Society.
