摘要

CuCeOx composite catalysts for the catalytic conversion of dimethylformamide were prepared by controlling the amount of Cu using chemical vapor deposition, and the physical and chemical properties and catalytic performance of the CuCeOx composite catalysts were characterized by X-ray diffraction analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy. The results showed that Cu–Ce bimetallic oxide thin film increases the specific surface area, pore volume, and pore diameter of the CeOx films. The Cu/Ce ratio can significantly affect the properties of the composite catalysts, such as activity, product selectivity, and stability, among which Cu50Ce50 shows the best overall performance in the catalytic reaction toward dimethylformamide.
