Effect of Calcination Temperature on the Activation Performance and Reaction Mechanism of Ce-Mn-Ru/TiO₂ Catalysts for Selective Catalytic Reduction of NO with NH₃.

ABSTRACT: In this study, anatase TiO₂-supported cerium, manganese, and ruthenium mixed oxides (CeO _x -MnO _x -RuO _x /TiO₂; CMRT catalysts) were synthesized at different calcination temperatures via conventional impregnation methods and used for selective catalytic reduction (SCR) of NO _x with NH₃. The effect of calcination temperature on the structure, redox properties, activation performance, surface-acidity properties, and catalytic properties of the CMRT catalysts was investigated. The results show that the CMRT catalyst calcined at 350 °C exhibits the most efficient low-temperature (<120 °C) denitration activity. Moreover, the selective catalytic oxidation (SCO) reaction of ammonia is intensif
