Overall photosynthesis of H2O2 by an inorganic semiconductor

Abstract Artificial photosynthesis of H 2 O 2 using earth-abundant water and oxygen is a promising approach to achieve scalable and cost-effective solar fuel production. Recent studies on this topic have made significant progress, yet are mainly focused on using organic polymers. This set of photocatalysts is susceptible to potent oxidants (e.g. hydroxyl radical) that are inevitably formed during H 2 O 2 generation. Here, we report an inorganic Mo-doped faceted BiVO 4 (Mo:BiVO 4 ) system that is resistant to radical oxidation and exhibits a high overall H 2 O 2 photosynthesis efficiency among inorganic photocatalysts, with an apparent quantum yield of 1.2% and a solar-to-chemical conversion efficiency of 0.29%…
