摘　　要：使用半导体材料进行太阳能制氢是使用化石燃料制氢的替代方案。有机光催化剂由地球上大量存在的C、H和O等元素组成,因其通过分子工程可以调节电子性质,相比于无机催化剂更具有优势。然而,目前对其光催化氧化还原过程的关键性质的理解尚不完全,阻碍了向成本更低更具有竞争技术的进一步发展。综述了有机半导体光催化进展及机理的研究。从描述有机半导体的原理开始,概述了有机光催化剂析氢反应的研究现状,分析了光激发后的激子行为,并提出了提高有机半导体光催化制氢效率的策略,最后总结了共轭超分子和聚合物有机光催化剂的研究进展,并对光催化剂的发展提出了期待和展望。Utilizing semiconductor materials for solar-driven hydrogen production is an alternative to hydrogen generation using fossil fuels.Organic photocatalysts,composed of abundant elements such as C,H,and O on Earth,have the advantage over inorganic catalysts due to their tunable electronic properties through molecular engineering.However,the current understanding of the key properties of their photocatalytic oxidation-reduction process is not complete,hindering further development into more cost-effective and competitive technologies.This paper reviews the progress in organic semiconductor photocatalysis and research on its mechanisms.Starting with the description of charge transfer in organic semiconductors,it outlines the current state of research on the hydrogen evolution reaction(HER)of organic photocatalysts,analyzes the behavior of excitons after photoexcitation,and proposes strategies to improve the efficiency of hydrogen production by organic semiconductor photocatalysis.Finally,it summarizes the research progress on conjugated supramolecular and the development of organic photocatalyst is expected and prospected.
