The catalytic performance of NO removal was studied over Mn-Ce/TiO2 catalysts prepared by different preparation parameters, such as preparation method, manganese precursor, Mn/(Mn+Ce) molar ratio and calcination conditions.It was found that samples prepared by impregnation method, which had the largest surface area and highly dispersed active component particles, showed the best denitration activity.As manganese precursor, manganese nitrate and manganese acetate were more conducive to high denitration efficiency than manganese chloride.The highest NO conversion of 92% is achieved at the Ce/(Mn+Ce) molar ratio of 0.15, 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.
