Complex metal oxide catalyst, method of preparing the catalyst, and method of preparing dimethylcarbonate using the catalyst |
摘要 |
PURPOSE: A complex metallic oxide catalyst containing a zinc oxide and a cerium oxide, a producing method thereof, and a producing method of dimethyl carbonate using thereof are provided to reduce the reaction time for reaching the maximum yield of the dimethyl carbonate. CONSTITUTION: A complex metallic oxide catalyst contains a composite of a zinc oxide(ZnO) and a cerium oxide(CeO2). A molar ratio of the zinc oxide moiety and the cerium oxide moiety is 0.9:0.1-0.1:0. A producing method of the complex metallic oxide catalyst comprises the following steps: preparing a precursor solution by dissolving zinc oxide and cerium oxide precursors in a first solvent; dissolving solid acid in a second solvent to obtain a solid acid solution; mixing the precursor solution and the solid acid solution to obtain a catalytic formation solution; heat-drying the catalytic formation solution to obtain solid materials; and plasticizing the solid materials.
