摘要：

A simple method to prepare Cu2+ doped mesoporous TiO2 with improved visible sensitive photocatalytic activity is reported The mesoporous samples were characterized by low angle and wide angle X-ray diffraction (XRD), transmission electron microscopy (TEM), N-2 adsorption-desorption, X-ray photoelectron spectra (XPS) and UV-visible absorbance spectroscopy The degradation of methylene blue under visible light irradiation was investigated to evaluate the photocatalytic activity of these materials. Analytical results demonstrate that Cu2+ doping amount is crucial to affect the photocatalytic ability of the mesoporous titania Among the samples, 0 05 at.% Cu2+ doped mcsoporous TiO2 exhibits the highest photocatalytic activity (C) 2010 Elsevier Inc All rights reserved
