Abstract:

CeO₂ nanobundles were obtained by the microwave homogeneous precipitation method using cerium nitrate and urea as raw materials. Ag nanoparticles were obtained by the microwave solvolthermal method using silver nitrate, PVP and ethanol as raw materials. Nanostructured Ag/CeO₂ was prepared by the impregnation method. The products were characterized by X-ray diffraction, SEM, TEM, UV-vis spectrum, BET. The photocatalytic properties of CeO₂ and Ag/CeO₂ nanomaterials were evaluated by degradation of methyl orange. The results show that the photocatalytic degradation of modified cerium oxide modified by nano silver on methyl orange is significantly improved. For the Ag (0.1 wt%)/CeO₂ material, the degradation rate on methyl orange is up to 83.2% under visible light irradiation for 1h. The catalytic activity of nanostructured Ag (0.1 wt%)/CeO₂ in dye decolorization is substantially higher than the standard reference TiO₂ P25.
