英文摘要	cdse/tio2 nanotube array (tio(2)nta) film was modified by nixco3-x,o-4 through the method of ammonia-evaporation induction growth. the films were characterized by x-ray diffraction, field emission scanning electron microscopy, energy dispersive spectroscopy, x-ray photoelectron spectroscopy and uv-vis diffuse reflectance spectroscopy. to characterize the photoanodes activity of photoelectrochemical oxidation of water, the chopped linear sweep voltammetry was performed in a three-electrode system under simulated solar irradiation. the results show that cdse/tio(2)nta is covered by a thin layer of nixco3-x,o-4 with the spinel structure in which ni and co are both in divalent and trivalent states. the modification of nixco3-x,o-4 on the cdse/tio(2)nta can lower the overpotential of water oxidation by about 430 mv compared with the cdse/tio(2)nta. the introduction of ni into the structure of co3o4 leads to the surface enhancement of trivalent cations (ni3+ and co3+) and consequently facilitates the oxidation of water.
