Abstract
Direct decomposition of NOx 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, NOx 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 NOx decomposition over Fe–Mn/H-beta. The coexistence of manganese and iron enhances the dispersion and lowers the crystallinity of both metal oxides.
