Project 85: Photocatalytic Production of H2O2 on Modified C3N4 under Simultaneous Sunlight

Prof. Mingce Long

Project Description and Objectives:

H2O2 is one of the fastest growing industrial chemicals in the world. In the recent ten years, it has been widely used as a multi-purpose environmentally friendly oxidant in the biological process, water purification and chemical industry since it only emits water as a final byproduct. Industrial production of H2O2 is through anthraquinone oxidation which is limited by the high energy input and tedious steps for multiple hydrogenation and oxidation reactions. It is still challenging but highly demanding to produce H2O2 in a facile, clean, and safe way. Photocatalytic production of hydrogen peroxide (H2O2) using water and molecular oxygen as the sole material source is a promising and sustainable solar fuel approach. However, the efficiency is limited by the low efficiency of oxygen reduction reaction (ORR) in H2O2 formation and the simultaneous decomposition of H2O2. C3N4 is a promising visible light-driven photocatalyst for H2O2 production. In this study, we plan to synthesize highly active C3N4 by improving crystallinity and doping single atoms. The prepared catalysts will be fully characterized. The performance for H2O2 production and enhanced mechanism will be explored.
