CuO-CeO{sub 2} binary oxide nanoplates: Synthesis, characterization, and catalytic performance for benzene oxidation
- State Key Laboratory of Multiphase Complex System, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190 (China)
This work reports the first synthesis of CuO-CeO{sub 2} binary oxides with a plate-like morphology by a solvothermal method. The as-prepared CuO-CeO{sub 2} nanoplates calcined at 400 {sup o}C were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectrum, and tested for catalytic oxidation of dilute benzene in air. Various structural characterizations showed that large amounts of copper species were exposed on the CuO-CeO{sub 2} nanoplate surface. The effect of the synthesis conditions on the structure of the product, as well as the growth process of the nanoplates, has been studied and discussed. The CuO-CeO{sub 2} nanoplates exhibited an excellent catalytic activity for benzene oxidation despite its relatively low surface area and could catalyze the complete oxidation of benzene at a temperature as low as 240 {sup o}C.
