MoO3 modified CeO2/TiO2 catalyst prepared by a single step sol-gel method for selective catalytic reduction of NO with NH3

A MoO3 modified CeO2/TiO2 catalyst was prepared by a single step sol-gel method for selective catalytic reduction of NO with NH3. The experimental results indicates that MoO3 modified CeO2/TiO2 catalyst exhibited higher SCR activity and resistance to 10% H2O and 1000 ppm SO2. From the characterization results, it can be concluded that good physical properties, highly dispersed active species of Ce and Mo, more appearance of Ce3+ and chemisorbed oxygen, strong interaction among ceria, molybdenum and titania, and high oxygen storage capacity might contribute to the excellent deNO(x) performance of CeO2-MoO3/TiO2 catalyst prepared by a single step sal-gel method.
