| 英文摘要 | the oxygen reduction reaction (orr) is a complex process. this is particularly the case for carbon-supported electrocatalysts in alkaline electrolytes, because carbon can catalyze the orr via a two-electron transfer to generate hydroperoxide (ho2-), which subsequently undergoes either chemical decomposition to generate o-2 and oh- (hodr) or electrochemical reduction to oh- (horr). in this study, we elucidated the orr pathway on a series of carbon-supported manganese oxides, which have been extensively studied as electrocatalysts in alkaline electrolytes. a comparison of the turnover frequencies of the hodr and horr showed that although an apparent four-electron transfer process was identified when the ho2- yield was measured using the rotating ring disk electrode technique, the real orr pathway involved a two-electron transfer process to generate ho2-, with subsequent chemical decomposition of ho2. these results will help us to understand the intrinsic catalytic behavior of carbon-supported transition-metal oxides for the orr in alkaline electrolytes.
