摘　　要：以不锈钢为基底,采用化学复合镀的方法制备了Ni–P/TiO2膜,然后采用阴极电沉积的方法在其基础上制备了Ni–P/TiO2/Cu2O复合膜。通过X射线衍射和紫外–可见光谱对Ni–P/TiO2和Ni–P/TiO2/Cu2O复合膜进行了表征,并以甲基橙模拟有机污染物,在可见光下测试了其光催化活性。结果表明,TiO2/Cu2O复合膜的光催化性能有较大程度的提高;在相同的条件下,甲基橙在Ni–P/TiO2膜上的降解率只有10.8%,而在Ni–P/TiO2/Cu2O复合膜上的降解率达到65.2%。A Ni-P/TiO2/Cu2O composite film was prepared on stainless steel substrate through electroless composite plating of Ni-P/TiO2 film followed by cathodic electrodeposition of Cu2O. The Ni-P/TiO2 and Ni-P/TiO2/Cu2O composite films were characterized by X-ray diffraction and UV-Vis spectroscopy, and the photocatalytic activity of the Ni-P/TiO2 and Ni-P/TiO2/Cu2O composite films was tested with methyl orange as simulated organic pollutant under visible light irradiation. The results showed that the photo- catalytic property of the Ni-P/TiO2/Cu2O composite film is greatly improved. The degradation rate of methyl orange on the film of Ni-P/TiO2 is only 10.8%, but 65.2% on the composite film of Ni-P/TiO2/Cu2O.
