Preparation and Photocatalyst of Ce/Zn Composite Oxide

摘要

With abscibe acid as combustion agent, Zn(NO3)27H_2O and Ce(NO3)36H_2O as raw material, the CeO2-ZnQ composite oxide was synthesized by an novel combustion method. The experiment investaged the effect of molar ratio of combustion agents, Zn and Ce on composite oxides. The samples were characterized by XRD, SEM, IR, UV. The molar ratio of Ce, Zn and combustion agents is different, the composite oxides possess various morphology and properities. The photocatalytic experiment of composite oxide showed that under the optimal photocatalytic condition Methylene blue solution is completely degradated to need 240 min and under the optimal decoloring condition Methylene blue solution is completely decolorized to need 180 min.
