Abstract:
Research progress of CuO-CeO2-based catalysts for preferential oxidation of CO in hydrogen-rich gas is reviewed in this paper. The present status of CuO-CeO2-based catalysts is analyzed. The effects of preparation technology,composition optimization,additive modification and carrier promotion on catalytic properties of CuO-CeO2-based catalysts are summarized. The active sites,catalytic mechanism,stability and deactivation of the catalysts are presented. The obstacles for practical application of the catalysts are pointed out. Based on the aforementioned analysis,the possible near future development trend of the CuO-CeO2-based catalysts is forecasted.
