Graphene Quantum Dots‐Modified Resorcinol‐Formaldehyde Resin for Efficient Hydrogen Peroxide Production

Abstract

Photocatalytic production of hydrogen peroxide (H2O2) with water and oxygen as clean source is considered to be a sustainable strategy. Resorcinol‐formaldehyde (RF) resin has attracted much attention as a promising polymeric photocatalyst, but the inefficient charge transfer restricts its corresponding photocatalytic efficiency. Herein, the design and synthesis of graphene quantum dots (GQDs) modified RF (RF‐GQDs) composite via freeze‐drying method are reported. The improvment of the RF‐GQDs composite charge separation efficiency is achieved through the combination electrostatic interaction between GQDs and RF, thus greatly enhancing photocatalytic performance. The optimal RF‐GQDs display the best photocatalytic H2O2 production activity of 2.45 mmol h−1 g−1, which is 5.1 times that of bare RF (0.48 mmol h−1 g−1). This work might contribute to a new way for the development of RF‐based ploymeric photocatalysts for efficient photocatalytic H2O2 production.
