Abstract

Abstract

A CeO₂-Fe₂O₃/TiO₂ catalyst was prepared by impregnation method. The effect of CeO₂ loading on the selective catalytic reduction of NO was studied. As a comparison, the catalyst in same optimum component proportion as above catalyst was also prepared by sol gel method. The BET, XRD, SEM and XPS were used for the catalyst characterization. The experimental results show that the catalyst of 10% CeO₂ and 3% Fe₂O₃ by impregnation method has an optimal performance up to the reduction efficiency of 96.65%. The catalyst by sol gel method has better denitration performance than that by impregnation method, reaching 99.36% of efficiency. The characterization results show that all the 10%-3%CeO₂-Fe₂O₃/TiO₂ catalysts made by impregnation method or by sol gel method have the advantages of larger specific surface area, better dispersity of active ingredient, and better oxygen storage capacity.
