H2O2 is a green oxidant, which is widely used in environmental protection, chemical production, daily disinfection and other fields. The traditional anthraquinone process has high energy consumption and is easy to produce toxic by-products. Although photocatalytic technology has the advantage of zero energy consumption, its low two-electron water oxidation ability seriously inhibits the efficiency of direct total synthesis of H2O2 from water and air. Based on this, Professor Ye Liqun developed a COF photocatalyst based on bipyridine for direct synthesis of H2O2 from water and air. The chemical energy conversion efficiency of solar energy at 25 and 60 degrees is 0.57% and 1.08%, respectively. After 8 hours (average sunshine time 1 day), the H2O2 concentration is more than 5mM, which can be directly applied to the decomposition of organic pollutants and the inactivation of pathogenic microorganisms.
This achievement has been guided by the National Natural Science Foundation of China, "11"Innovation and Intelligence Introduction Base Fund and Professor Huang Yingping.
