N-doped Titanium dioxide (TiO2) nanotube arrays were characterized by scanning electron microscope (SEM),X-ray Diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) to analyse its surface morphology, crystal types and the doping behavior of nitrogen. The material was used as electrode for photoelectrocatalytic degradation of hexachlorobenzen under irradiation of simulated sunlight. The effects of photocatalysis, electrocatalysis, photoelectrocatalysis, the concentration of Na2SO4 and pH value on degradation of HCB were investigated.
