通过Fe3+分别把3种吨染料(xanthene)曙红Y(Eosin Y)、藻红B(Erythrosin B)、虎红(Rose-bengal)固定在TiO2表面制备xanthene-Fe3+-TiO2敏化催化剂.在可见光(λ≥420nm)下,以三乙醇胺为电子给体,3种xanthene-Fe3+-TiO2放氢活性明显高于Fe3+偶联前xanthene-TiO2.UV-vis吸收表征表明3种xanthene-Fe3+-TiO2在可见光的吸收比xanthene-TiO2更强.吸附实验和FTIR表征显示Fe3+均增加3种吨染料在TiO2的吸附量和吸附强度.因而,Fe3+偶联的光催化剂活性大大提高.讨论了吨染料结构对敏化TiO2催化荆活性的影响.
