摘要
光催化分解水是太阳能向化学能转换的一种重要方式,其中高效稳定光催化剂的研制至关重要.具有平面共轭结构的苝类有机小分子是一类富含π电子的n-型半导体,具有结构易修饰、可见光吸收强以及光热稳定性高等优点,近年来在光催化领域研究广泛.我们总结了4类含有苝环结构的有机小分子苝四甲酸二酐、苝二酰亚胺、苝单酰亚胺以及苝四酸的特点.此外,从分子结构修饰、构筑聚合物、金属辅助、与其它材料复合及改变组装条件这几种方式对材料在光催化分解水方面的研究进展进行了综述,并对含有苝环结构的有机半导体材料在光催化分解水方面存在的问题和前景进行了分析和展望.
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 ofπ-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.
