摘要
A very active catalyst of CuO/CeO_2 was made by adsorption-impregnation method for preferential oxidation of CO in H_2. The CO conversion is close to 100% and selectivity to CO oxidation is 96% over this catalyst at a low reaction temperature of 95 ℃ and a space velocity of 40000 cm^3·g^(-1)·h^(-1) in the reaction mixture of 1%CO, 1%O_2, and 50%H_2 balanced with N_2. The effect of preparation conditions on catalytic performances was investigated. The catalytic performance of the CuO/CeO_2 catalysts was compared with that of other CO preferential oxidation catalysts reported in literature.
