Photocatalytic hydrogen evolution (PHE) presents a promising way to solve the global energy crisis. Metal-free carbon nitride (CN) and organic semiconductors photocatalysts have drawn intense interests due to their fascinating properties such as tunable molecular structure, electronic states, strong visible-light absorption, low-cost etc. In this paper, the recent progresses of photocatalytic hydrogen production based on organic photocatalysts, including CN, linear polymers, conjugated porous polymers and small molecules, are reviewed, with emphasis on the various strategies to improve PHE efficiency. Finally, the possible future research trends in the organic photocatalysts are prospected.
光催化析氢（PHE）为解决全球能源危机提供了一条很有前景的途径。无金属的氮化碳（CN）和有机半导体光催化剂因其具有如可调节的分子结构、电子态、强可见光吸收能力、低成本等迷人特性而备受关注。本文综述了基于有机光催化剂（包括CN、线性聚合物、共轭多孔聚合物和小分子）的光催化制氢研究进展，重点介绍了提高光催化析氢效率的各种策略。最后，展望了有机光催化剂未来可能的研究趋势。
