Research Progress in Photocatalytic Decomposition of Water Using Organic Semiconductors Containing Perylene Rings
Photocatalytic water decomposition is an important way to convert solar energy to chemical energy,in which the development of highly efficient and stable photocatalyst is very important.Perylene organic small molecules with planar conjugated structure are a class of π-electron rich N-type semiconductors,which have the advantages of easy modification,strong absorption of visible light and high photothermal stability,and have been widely studied in the field of photocatalysis in recent years.The characteristics of four types of perylene tetracarboxylic dianhydride,perylene diimide,perylene monoimide and perylene tetracarboxylic acid containing perylene ring structure are summarized in this paper.In addition,the research progress of photocatalytic water decomposition by molecular structure modification,polymer construction,metal-assisted,composite with other materials and changing assembly conditions were reviewed,and the problems and prospects of organic semiconductor materials containing perylene ring structure in photocatalytic water decomposition were analyzed and prospected.
