摘要
In the present paper, effect of iron on activity of catalyst CuO/CeO2 in selective CO oxidation in H-2-containing gases mixture was investigated. Catalysts were prepared by wet impregnation and calcination at 400 degrees C, characterized by ICP, BET, H-2-TPR, XRD and TEM. The addition of iron to Cu/CeO2 catalyst improved the catalytic activity and selectivity for CO oxidation. Discussion of the results showed that the synergistic effect is correlated to better reducibility and dispersion of copper in the presence of the iron metal additive. (C) 2010 Elsevier B.V.
