摘　　要：综述了本研究组近年来量子点人工光合成制氢体系的研究进展,重点从量子点与氢化酶模拟化合物、量子点与过渡金属离子、量子点敏化光阴极3个方面分析了影响制氢效率的主要因素,指出对光生电荷(电子和空穴)的有效捕获是提高人工光合成分解水制氢效率的关键,并展望了未来人工光合成发展方向。Artificial photosynthetic hydrogen evolution is a promising way for solar-to-fuel conversion, which is considered as an important means to solve human energy crisis and environmental pollution. This article reviews the progress of quantum dot artificial photosynthesis hydrogen evolution system, focusing on the analysis of hydrogen evolution efficiency, including quantum dots with hydrogenase mimics, transition metal, and sensitized photocathodes. Specifically, we point out that the capture of photogenerated charges(electrons and holes) plays a pivotal role in improving hydrogen evolution efficiency, and look forward to the development direction of artificial photosynthesis.
