摘要：

Nanostructured AgI/TiO2 photocatalyst was synthesized through deposition-precipitation using AgNO3, KI and Ti(OBU)(4). Then the photocatalyst was further treated by PdCl2 solution, which resulted in a color change from yellow to green and PdCl2 reacted with AgI as indicated by X-ray diffraction analyses. The diffusive reflectance UV-vis spectroscopy of this modified photocatalyst shows a remarkable enhancement of the absorption intensity in the range of visible light. As nanostructured AgI/TiO2 shows a considerable visible light photocatalytic activity for the photodegradation of methylene blue, PdCl2-modified AgI/TiO2 exhibits a much larger visible light photocatalytic activity for the photodegradation of methylene blue.
