文摘
- •
Mn-Nb/TiO2 catalyst has higher SCR activity and better Zn resistance than Mn/TiO2 catalyst.
- •
The modification of Mn/TiO2 catalyst by Nb could promote the adsorption of NH3 species and NOx species.
- •
The NH3-SCR reactions over Mn/TiO2 and Mn-Nb/TiO2 are all controlled by the L-H mechanism and the E–R mechanism.
