Preparation and performances of nanorod-like inverse CeO2-CuO catalysts derived from Ce-1,3,5-Benzene tricarboxylic acid for CO preferential oxidation

摘要

A facile one-pot strategy of using CeBTC MOF as template and precursor was explored to prepare rod-like inverse CeO2-CuO catalysts. The inverse CeO2-CuO catalysts were characterized by using techniques of N-2 adsorption and desorption, XRD, TEM, TPR and XPS. The results indicated that the rod-like inverse CeO2-CuO catalysts maintained the shapes of CeBTC MOF templates. The Cu0.71Ce0.29 catalysts exhibited excellent catalytic performance which was attributed to the strong synergistic effect between CuO and CeO2 and subsequent formation of reduced copper species.
