Abstract
The catalytic performance of NO removal was studied over Mn-Ce/TiO2 catalysts prepared by different preparation parameters, such as preparation method, Ce/(Mn+Ce) molar ratio and calcination temperature. It was found that samples prepared by co-precipitation method, which had the largest surface area and highly dispersed active component particles, showed the best denitrification activity. The highest NO conversion of 95% is achieved at the Ce/(Mn+Ce) molar ratio of 15% which is much higher than that of the pure manganese constituent. The increase of calcining temperature favored the crystallization of active components, leading to the decline of catalytic activity.
