Improvement of low-temperature catalytic activity over hierarchical Fe-Beta catalysts for selective catalytic reduction of NOx with NH3
TL;DR: In this paper, the pore structure, acidity and Fe sites of the hierarchical Fe-Beta and conventional F-Beta were investigated to identify the main factors leading to the difference in catalytic activity, and it was concluded that the improvement of NH3-SCR activity was not due to an intrinsic effect of specific structural characteristics, but was related to more Fe active sites and better dispersion of Fe species in the hierarchical FE-Beta.
