Abstract

Direct decomposition of NO_x in the presence of oxygen was investigated over a series of Fe-Mn/H-beta catalysts with Mn/Fe = 1 at temperature range from 523 to 773 K. When Mn is incorporated to Fe/H-beta, NO_x conversion is improved, and the active temperature window is lowered. 5%Fe-5%Mn/H-beta exhibits the highest activity among Fe-Mn/H-beta catalysts with Mn/Fe = 1. Neither O₂ nor CO₂ inhibition was observed in NO_x decomposition over Fe-Mn/H-beta. The coexistence of manganese and iron enhances the dispersion and lowers the crystallinity of both metal oxides.
