Abstract
Speciation of titanium in the CuO/TiO2 thin film (synthesized by radio frequency magnetron sputtering) during photocatalytic decomposition of CHCl3 has been studied by in situ X-ray absorption near-edge structural (XANES) spectroscopy. Little perturbation was observed in the Ti K-edge XANES spectra of the CuO/TiO2 during photocatalysis. However, by prolonging the UV/VIS radiation to 90 min, the copper K-edge white line absorbance was enhanced suggesting electron donation (from the encapsulated TiO2) to surface CuO, which was also observed by electron spectroscopy for chemical analysis (ESCA) spectroscopy.
