中文摘要：
用光还原方法制备了负载Cu的光催化剂Cu-TiO2，并通过染料Rose bengal敏化，制备了具有可见光活性的Rose bengal-Cu-TiO2光催化剂，通过可见光下光解水制氢考察了催化剂的活性，并利用XRD、UV-Vis等手段对样品进行了表征。实验表明：载Cu增强了TiO2对可见光的吸收，Cu负载量对催化剂活性有一定的影响，Cu的最佳负载量为5％（质量分数）。Cu的负载也增加了TiO2对染料的吸附强度和吸附量，从而提高了TiO2对可见光的吸收和光催化活性。但载Cu的TiO2催化剂的活性和传统的载贵金属Pt的TiO2催化剂相比，其光催化活性较低，有待进一步提高．
英文摘要：
The photocatalyst Cu-TiO2 was prepared by the method of light deoxidize. By dye-sensitization with rose bengal as sensitizer, we prepare the photocatalyst Rose bengal-Cu/TiO2 which has photoactivity under visible light.The photocatalytic activities of the catalysts were investigated by the photocatalytic hydrogen generation from water under visible light, and The photocatalyst were characterized by means of X-ray diffraction and UV-Vis absorption spectra. The result indicate that loading Cu enhance TiOa adsorption to visible light. Amount of loading Cu has some influence on the photocatalytic activity of photocatalyst, the optimal amount of Cu loading were 5wt%. The adsorption amount and intensity of Cu-TiO2 photocatalyst to dye rose bengal were enhanced compare with the pure TiO2, so the adsorption to visible light and photocatalytic activity of Cu-TiO2 were improved,but its photocatalytic activity was lower than Pt-TiO2 photocatalyst and need to be improved.
