A novel Mn-V-Ce/TiO2 catalyst for catalytic oxidation of nitric oxide was prepared by impregnation method. The effects of loading, carrier, calcining temperature, volume fractions of NO and O2, and space velocity on Mn-V-Ce/TiO2 catalytic oxidation of nitric oxide were studied, and the catalysts were characterized by BET and XRD analysis. The results show that the catalyst from calcination of 10%Mn-3%V2O5-20%CeO2/TiO2 at 300℃ for 6 h can obtain the optimal catalytic oxidation activity. When the volume fract...
