Co/Cu/Fe mixed oxides (Co/Cu/Fe-MOs) were prepared by calcination of Cu/Co/Fe hydrotalcites (Co/Cu/Fe-HTs) precursors. Their structure and morphology were characterized by XRD, TGA, IR and SEM. Co/Cu/Fe-MOs were used for selective catalytic reduction of NO by hydrocarbon. Their catalytic activities were studied by NOx analyzer. The results show that Co/Cu/Fe-MOs have homogeneous distribution of hexagon with particles size around 30~50nm and the specific surface areas are around 70~110 m2∙g–1. Cu2Co8Fe5-MOs sample exhibits the highest NOx conversion of 32%. Co/Cu/Fe-MOs with lower calcination temperature have higher catalytic activities.

The effects of Cu/Mn ratio on the activity and stability of Cu-Mn catalysts for the water-gas shift reaction (WGSR) were investigated. Activity tests showed that the Cu-Mn catalyst while the ration of Cu to Mn is 1:1 displayed higher activity and better stability than that of others catalysts. The BET , XRD and TPR results revealed that the Cu-Mn catalyst while the ration of Cu to Mn is 1:1 led to higher surface area, a more stable catalyst structure and suitable reduction performance, in turn leading to better catalytic behavior for the Cu-Mn catalyst.
