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.
