Abstract: A CdSe/foam nickel thin film electrode was prepared by depositing the CdSe thin film on the foam nickel surface with potentiostatic method. The morphology and composition of CdSe/foam nickel thin film electrode were characterized by SEM, UV-Vis diffusive reflectance spectra(DRS) and energy dispersive spectra(EDS). The chemical oxygen demand(COD) removal efficiency was investigated during the process of photoelectrocatalytic degradation of crystal violet. The results show that the COD removal efficiency of 0.001 g/L crystal violet can reach to 84.3% when using the CdSe/foam nickle thin film electrode as working electrode and catalyst(deposition time is 30 min) under the following conditions:0.01 mol/L supporting electrolyte of NaCl, anodic bias potential of 0.4 V(vs.SCE), irradiation for 120 min with two incandescent lamps(100 W).
