The influence of modification of AlCl3 on activity of photocatalytic catalyst rose bengal-TiO2 generating hydrogen under visible light

用浸渍法制备了Rose bengal-Pt-TiO2和Rose bengal-AlCl3-Pt-TiO2光催化剂,通过可见光下光解水制氢考察了催化剂的催化活性.染料Rose bengal的敏化使TiO2在可见光照射下有较强的吸收和活性.催化剂Rose bengal-AlCl3-Pt-TiO2光催化活性高于Rose bengal-Pt-TiO2.其原因是经过AlCl3修饰的TiO2可以提高对染料Rose bengal的吸附量和吸附强度, 从而提高了TiO2的可见光催化活性.
