摘要：

A TiO2-SiO2 mixed oxide was obtained by a co-precipitation method. MnOx-CeO2/TiO2-SiO2 were prepared by an impregnation method and their activity towards the selective catalytic reduction of NO with NH3 at low temperature were evaluated. Compared with pure TiO2, TiO2-SiO2 exhibited an evidently larger surface area and pore volume, and a smaller average pore diameter with narrow distribution. The NO conversion of the MnOx/TiO2-SiO2 catalyst could be improved by the addition of an appropriate amount of CeO2 in the temperature range of 100-180 degrees C. MnOx-CeO2/TiO2-SiO2 with 10 wt-% CeO2 showed the highest activity with 96% NO conversion at 180 degrees C.
