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.
