Enhancement of the Photocatalytic Reactivity of Unique Rectangular Column-structured TiO2 Photocatalysts by Incorporating Nanosized Metal Particles

摘要

Highly efficient rectangular column-structured TiO2 photo-catalysts have been developed by loading various metal nanopar-ticles on TiO2,such as copper (Cu/TiO2)or platinum (Pt/TiO2),by a photodeposition method.It was observed that with a Cu-loaded Cu/TiO2 photocatalyst,there was less decrease in the photocatalytic activity due to the poisoning of the photo-formed inorganics than with unloaded TiO2 catalysts.
