摘　　要：分别测试了pH、载Pt、占顿染料上溴的个数等不同条件下的染料敏化光催化制氢行为。结果发现:pH为中性、载Pt的TiO_2的催化下制氢性能较好;占顿染料上溴的个数越多,制氢性能越高,特别是在载Pt的条件下,四溴荧光素(曙红Y)染料敏化的氢气产生量在2 h内可达75.2μmol,但由于脱溴导致稳定性偏差。The photocatalytic hydrogen production sensitized by xanthene dyes under different pH values, Pt loading and the number of bromine on xanthane were investigated. The results showed： the performance of hydrogen production was better when the p H value was neutral using Pt-loaded TiO_2 as catalysts; with increase of the number of bromine on the xanthene dyes, the hydrogen production performance enhanced, with a relatively high amount of hydrogen, 75.2 μmol within 2 h fortetrabromofluorescein dye（Eosin Y） in the presence of Pt-loaded TiO_2, while the stability was poor because of debromination.
