Abstract

The apparent four-electron oxygen evolution catalyzed by Co₃O₄ nanosheets indeed proceeds via a double two-electron process, because the generated Co^III/Co^IV redox couple can synchronously, quickly, and effectively oxidate the intermediate OOH^ads, and thus accelerate O^ads₂ generation.
