摘要：

This communication describes an efficient co-catalyst Co3O4 nanoparticle with a tunable two-electron water oxidation reaction pathway in photoelectrochemical H2O2 production. The photoluminescence measurement explains that the promotion effect is due to the accelerated activation of water to OH. The increased Faraday efficiency of H2O2 for the Co3O4/ WO3 sample also verifies that the promotion effect to a two-electron water oxidation reaction of Co3O4 is universal to other semiconductor photoanodes.
