Abstract:
... Industry for producing the vital chemical hydrogen peroxide (H₂O₂) requires drastically reductions in energy consumption and environmental pollution. Solar chemical conversion from O₂ to H₂O₂ is considered to be the most promising alternative method, nevertheless, weak energy coupling between photo-charges and adsorbed species limits the yield of H₂O₂. Herein, we demonstrate that oxygen vacancy-ri ...
