摘要：

We studied the effect of urea on TiO2-CeO2 and paracetamol photodegradation. The contribution of TiO2, CeO2, and urea was analyzed by simplex-centroid mixture. Solid-state combustion at 500 C was the method of synthesis. All samples were characterized by X-ray diffraction, nitrogen adsorption/desorption, Uv spectroscopy, and scanning electron spectroscopy (SEM). According to the results, urea influences particle morphology. Bandgap decreases due to interactions with residual urea carbon. The surface area depended on the crystallinity of the samples. The value of the kinetic constant increased as a function of the amount of urea. The selectivity to CO2 was the roll of cerium oxide.
