Regulating the substituent of the electron-acceptor in a D–A system for boosting H2O2 photosynthesis from air and water

Abstract

We report here an approach of regulating the substituent of the electron-acceptor in a D–A system to promote H₂O₂ photosynthesis from water and air. Without any sacrificial agent, the Cl-substituted material was found to give the best photocatalytic performance with a H₂O₂ production rate of 4048 μmol g⁻¹ h⁻¹, representing a 2.2- and 4.6-fold enhancement relative to the other two counterparts.
