Co3O4 nanosheets as a high-performance catalyst for oxygen evolution proceeding via a double two-electron process.
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 generation.
