Sustainable photocatalytic production of hydrogen peroxide from water and molecular oxygen

Abstract

We report the direct production of H₂O₂ from O₂ and H₂O using a heterogeneous catalyst made from non-toxic materials using light as the sole energy source for the process. Photocatalytic production of H₂O₂ is demonstrated using light energy without the need for additional chemical energy (sacrificial compounds) or applied electrical potential. Fine-tuning of catalyst architecture and interface design enables exceptional photocatalytic activity.
