Progress in Photocatalytic Production of Hydrogen Peroxide
Hydrogen peroxide is a kind of multi-functional green chemical with high value,which is widely used in various industrial manufactory,clean energy and fuel fields.Industrial production of H2O2 by traditional anthraquinone method not only consumes much energy,but produces a variety of chemical wastes,resulting in huge environmental pollution.Photocatalytic technology is a new approach for producing H2O2 in recent years,which is green and environmentally friendly.However,it still suffers from low photocatalytic activity,low yield of H2O2 and slow reaction.The basic principle of photocatalytic preparation of H2O2 is briefly described,the research progress of photocatalytic preparation of H2O2 is introduced,the structure and photocatalytic performance of different photocatalytic materials are compared and analyzed,and the structure regulation and performance improvement approaches and strategies of photocatalytic materials are summarized.Finally,the main problems in this research field are proposed,and the future development direction is prospected.
