Electro-catalytic effect of manganese oxide on oxygen reduction at teflonbonded carbon electrode ZHOU De-bi(周德璧), L? Xin-kun(吕新坤), LIU Dan-ping(刘丹平) School of Chemistry and Chemical Engineering...; Abstract: Oxygen reduction(OR)on Teflon-bonded carbon electrodes with manganese oxide as catalyst in 6 mol/L KOH solution was investigated......
, 1-1 Hibarigaoka, Tempakucho, Toyohashi 441-8580, Japan) Abstract:Temperature programmed reduction (TPR) study was carried out for CeO2/Al2O3 and CeO2/ZrO2 catalysts to evaluate oxygen storage property induced by a facile redox cycling of Ce ion. The CeO2/ZrO2 catalyst possesses excellent oxygen storage activity at 373 K after reduction above 1173 K although the oxygen storage of CeO2/Al2O3......
