Photoelectrochemical oxidation featuring strong oxidation performance, low-volume application, and environmental compatibility has been an effective method for degradation of refractory organic pollutants. To further increase the effect and application potential of the photoelectrochemical oxidation method, it is essential to develop the electrode with high photoelectrochemical activity and strong stability[1]. In this study, Ti/TiO2 photoelectrode was prepared with anodic oxidation of Ti foil electrode and then the photoelectrocatalytic (PEC) degradation of 2-nitrophenol (2-NP) was performed via this electrode, comparing with direct photolysis, electrochemical and photocatalytic degradation by ultraviolet light. 2-NP concentration monitoring was carried out with differential pulse voltammetry. Results showed that PEC degradation has highest effect on concentration decreasing of 2-NP at solution. Finally, effects of solution pH and applied potential on degradation efficiency were investigated.
