Title
Low-temperature selective catalytic reduction of NO with NH3 over ordered mesoporous MnxCo3 − xO4 catalyst
Abstract

•The mesoporous MnCo2O4 catalyst was synthesized by nanocasting method.•The mesoporous catalyst was first used in SCR reaction.•The MnCo2O4 catalyst showed much better SCR activity than the MnO2 catalyst.•Catalytic activities depend on the strong interaction of manganese and cobalt oxide species.

The ordered mesoporous materials (MnO2, Co3O4 and MnCo2O4) were successfully synthesized by the nanocasting method and tested for the selective catalytic reduction (SCR) of NO with NH3. The MnCo2O4 catalyst had higher N2 selectivity, more extensive operating-temperature window, and high SO2 tolerance. The TEM results suggested that the special porous structure provided a larger surface area to adsorb and activate reaction gases. The H2-TPR and NH3-TPD results demonstrated that the MnCo2O4 catalyst possessed a more powerful reducibility and stronger acid strength.
