摘要：

The effect of the addition of CeO2 on the structural and textural properties of TiO2 and TiO2-CuO samples calcined at different temperatures was analyzed. The structural and textural transformation when the temperature of calcination was varied was followed by X-ray diffraction, Raman spectroscopy, and N-2 adsorption techniques. The addition of CeO2 to the TiO2 and TiO2-CuO samples decreases the anatase-rutile phase transformation when compared with the case of pure TiO2. This decrease observed for the phase transformation prevents the substantial surface loss and pore growth associated with this process.
