Abstract
CuO/CeO 2 catalysts, with 7 and 9 wt.% copper loading was prepared by wet impregnation, and later was washcoated over cordierite monoliths in order to study their performance in CO-PROX reaction. The powder sample with low copper loading shows high concentration of easily reducible copper species. SEM images of the monoliths show an average thickness of 9 and 12 μm of the catalyst layer for 7% and 9% copper containing samples. EDX analyses suggested that copper has been deposited non-uniformly on the ceria surface. In the absence of CO 2 and H 2O, monolith washcoated with 7% Cu loaded catalyst shows better performance than its 9% counterpart in terms of activity and selectivity towards CO 2 in CO-PROX reaction. However, CO 2 substantially inhibits the activity and selectivity of both monoliths, in particular 7% Cu loaded catalyst. Also, H 2O inhibits the activity and selectivity of both monoliths, although in lower extent than that of CO 2.
