Research progress in external fields synergistic structural regulation photocatalytic systems
This article reviews the mechanisms and latest research progress of structural regulation en-hanced photocatalysis and enhanced photocatalysis through external fields synergistic structural regula-tion,and the advantages and disadvantages of each external field enhanced photocatalysis are discussed.Photocatalysis is a technique that converts solar energy directly into chemical energy.It has great potential in environmental governance and energy crisis resolution.The rapid recombination of photoelectron-hole pairs greatly limits the photocatalytic efficiency of photocatalysts.Through structural regulation,such as el-ement doping,noble metal loading,construction of heterojunction structure,can greatly improve the effi-ciency of photocatalysis,but their application still has strong limitations.In recent years,the application of external fields(mechanical stress,microwave,temperature gradient,electric field,magnetic field,etc.)in photocatalytic reactions has significantly improved the efficiency of photocatalysis and broadened the ap-plication range of photocatalysis.The prospects and challenges of enhanced photocatalysis through external fields synergistic structural regulation are discussed.
