A series of the CeO2-based catalysts loaded on TiO2, TiO2-SiO2, TiO2-Al2O3, and TiO2-SiO2-Al2O3 supports were prepared by incipient impregnation method for the selective catalytic reduction (SCR) of NO by NH3 in the presence of oxygen. The SCR activities of the catalysts with different supports increases in the order of Ce/TiO2 < Ce/TiO2-20SiO(2) approximate to Ce/TiO2-3.5Al(2)O(3) < Ce/TiO2-20SiO(2)-3.5Al(2)O(3). The Ce/TiO2-20SiO(2)-3.5Al(2)O(3) catalyst showed 100% NO conversion in the temperature range of 250-425 degrees C and 100% N-2 selectivity in the whole temperature range. The catalytic activity of Ce/TiO2-20SiO(2)-3.5Al(2)O(3) exhibited good stability and strong resistance to SO2 and H2O poisoning. The co-introduction of SiO2 and Al2O3 into TiO2 could increase the amount of chemisorbed oxygen and Lewis acid sites on the surface of catalyst, which should be responsible for the excellent SCR activity.
