Fe-Mn/Al2O3 catalysts for low temperature selective catalytic reduction of NO with NH3

An Fe-Mn/Al2O3 catalyst with 8 wt% Fe and 8 wt% Mn loadings exhibited higher ABET, enhanced dispersion of active species, improved redox properties and acidity, lower binding energy, higher Mn4+/Mn3+ and more adsorbed oxygen species, which gave superior low temperature catalytic activity.
