摘　　要：采用阳极氧化和水热法制备CuS二氧化钛纳米管复合电极,采用扫描电子显微镜(SEM),X射线衍射(XRD)等方法进行表征。结果表明,该方法成功制备了CuS二氧化钛纳米管复合电极。研究了复合电极对磷系阻垢剂的光电催化性能,同时详细研究了掺杂物浓度(CuCl2、Na2S2O3)、水热时间、降解电压对CuS二氧化钛纳米管复合电极的影响。研究结果表明:半导体耦合掺杂的二氧化钛纳米管的的光电化学性质,优于纯的二氧化钛。A well-aligned CuS /TiO2 nanotube array electrode with light activity was successfully prepared using a two-step electrochemical process of anodization and hydrothermal method. Its morphology and chemical composition was characterized by scanning electron microscope and X-ray diffraction. The nanoparticles were highly dispersed inside the TiO2 nanotube and obtaining titania nanotube composite electrode. Composite electrode was studied on phosphorus photoelectric catalysis performance of scale inhibitors. In addition,we discussed the influence on the electrode properties of CuS /TiO2 nanotube array electrode nanotube array from the doping concentration of CuCl2 and Na2S2O3. Hydrothermal time,voltage degradation. The research results show that the coupling doped semiconductor photoelectric and chemical properties of the titanium dioxide nanotubes,is superior to pure titanium dioxide.
