Title: Preparation of CuO-CeO_2 by modified citrate method and its catalytic activity for low temperature CO oxidation
Abstract: CuO-CeO2 catalyst was prepared by modified citrate method using ethanol instead of water as the solvent.The catalyst was characterized by N2 adsorption,XRD and H2-TPR and its catalytic activity for low temperature CO oxidation was investigated in a microreactor-GC system.The results indicated that there existed only larger CuO particles less associated with ceria in the catalyst prepared by conventional method,while there existed highly dispersed CuO with strong interaction with ceria in the catalyst prepared by the modified method;the latter thus had higher catalytic activity for low temperature CO oxidation.
