Understanding activity trends in electrochemical water oxidation to form hydrogen peroxide

Electrochemical production of hydrogen peroxide (H(2)O(2)) from water oxidation could provide a very attractive route to locally produce a chemically valuable product from an abundant resource. Herein using density functional theory calculations, we predict trends in activity for water oxidation tow...

description Electrochemical production of hydrogen peroxide (H(2)O(2)) from water oxidation could provide a very attractive route to locally produce a chemically valuable product from an abundant resource. Herein using density functional theory calculations, we predict trends in activity for water oxidation towards H(2)O(2) evolution on four different metal oxides, i.e., WO(3), SnO(2), TiO(2) and BiVO(4). The density functional theory predicted trend for H(2)O(2) evolution is further confirmed by our experimental measurements. Moreover, we identify that BiVO(4) has the best H(2)O(2) generation amount of those oxides and can achieve a Faraday efficiency of about 98% for H(2)O(2) production.
