Abstract
The electrochemical properties in aqueous solution of composite materials made from nanocrystalline anatase TiO2 with CuBr and CuO are reported. CuO–TiO2 composite samples are prepared by a novel route based on oxidation of CuBr–TiO2. The corrosion of CuBr–TiO2 composite electrodes prevents a detailed electrochemical analysis. The data on CuO–TiO2 composites are consistent with the presence of a surface layer of TiO2 nanoparticles. A Mott–Schottky analysis gives a flat-band potential of −0.5 V/NHE (pH = 6) and a low carrier density of 1014cm−3.
