摘要：
High-dispersed surface anatase TiO2 modified CuOX-CeOX catalysts were prepared by wet impregnation method and their activities for selective catalytic reduction of NO with NH3 were investigated. The structure of TiO2 was found to influence the interactions between active components and support, which enhanced the NO adsorption and oxidation on catalyst surface under optimal conditions, thus activated the fast SCR reaction at a low temperature of 100 degrees C.
