摘　　要：染料敏化是拓展宽禁带光催化剂激发波长范围、有效利用太阳光中可见光部分的重要手段.本文介绍了染料敏化分解水制氢的基本原理,综述了染料敏化剂、基质或载体、染料与基质的相互作用、产氢助催化剂以及电子牺牲剂的研究进展.并对光敏化体系中电荷转移途径及稳定性问题进行了讨论.Dye sensitization is an important strategy for broadening the excitation wavelength range of wide- band-gap photocatalysts to use visible light from the sun. In this paper, the primary principle of dye-sensitized water splitting for hydrogen production was introduced, and the research progress in dye sensitizers, sensitized matrixes or supporters, the interaction between dyes and matrixes, co-catalysts for hydrogen evolution, and sacrificial electron donors were all reviewed. Moreover, the pathways of charge transmission and stability issues in dye-sensitized systems were discussed.
