摘要：
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 N-2 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 H-2-TPR and NH3-TPD results demonstrated that the MnCo2O4 catalyst possessed a more powerful reducibility and stronger acid strength. (C) 2015 Elsevier B.V. All rights reserved.
