Abstract

The CeCuOx composite catalysts for the catalytic conversion of dimethyl formamide were prepared and catalyzed by the sol-gel method with a controlled amount of Cu. The physical and chemical properties and catalytic performance of the CeCuOx composite catalysts were characterized by X-ray diffraction analysis, N2 adsorption-desorption, scanning electron microscopy, X-ray photoelectron spectroscopy, and H2-programmed step-up reduction. The results indicate that the doping of Cu increases the particle size of the CeOx support and enhances the relative content of Ce3+ species on the CeOx surface. The Cu/Ce ratio significantly influences the activity, product selectivity, and stability of the composite catalyst. Among them, Cu80Ce20 exhibits the best overall performance in the catalytic reaction of dimethylformamide.

溶胶-凝胶法催化氧化二甲基甲酰胺的研究
摘要 采用溶胶-凝胶法制备了催化转化二甲基甲酰胺的 CeCuOx 复合催化剂。通过 X 射线衍射分析、N2 吸附-解吸、扫描电子显微镜、X 射线光电子能谱和 H2 程序升压还原等方法对 CeCuOx 复合催化剂的理化性质和催化性能进行了表征。结果表明,Cu 的掺杂增加了 CeOx 支持物的粒度,并提高了 CeOx 表面 Ce3+ 物种的相对含量。Cu/Ce 比对复合催化剂的活性、产物选择性和稳定性有显著影响。其中,Cu80Ce20 在二甲基甲酰胺催化反应中表现出最佳的综合性能。
