摘要：

The TiO2/Pt and TiO2-Pt/CuS nano-crystalline photocatalystes were prepared by electrochemical deposition of Pt and chemical deposition of CuS on TiO2 nanotube array electrode fabricated using anodic oxidation method. Scanning electron microscope (SEM) and transmission electron microscopy (TEM) were used to characterize the morphology of TiO2, TiO2-Pt and TiO2-Pt/CuS. Energy dispersive spectrometer (EDS) was used to investigate the elemental structures of photocatalystes. The photocatalytic activities of the prepared samples were investigated by using photocatalytic degradation of H2O and organic compounds as model reactions in solution. The results showed that TiO2 nanotube array can maintain the original morphology under Pt electrochemical deposition and CuS chemical deposition. Pt can deposit in the TiO2 nanotube. Some CuS can form a mixed-phase with Pt on the surface of the TiO2 nanotube array electrode. The results obtained from the hydrolysis and the degradation of organic compounds showed that the order of photocatalytic activities of the prepared samples was TiO2-Pt/CuS>TiO2-Pt>TiO2. ©, 2015, Journal of Functional Materials.
