Cover Story: ERI and SSZ-13 were subjected to post-synthetic treatments (depending on the zeolite topology) to create micro/mesoporous materials. The post-synthetic modification of the investigated zeolites varied their catalytic activity in the selective catalytic reduction of NO with ammonia (NH3-SCR-DeNOx). Regarding the Cu-containing ERI, the NO conversion was higher for catalysts with modified supports. For the Cu-containing SSZ-13 catalysts (with post-modified zeolites), a lower NO conversion in NH3-SCR-DeNOx was observed. According to the physico-chemical characterization, the modification of the supports resulted in the presence of different amounts and kinds of copper species (especially isolated Cu2+ and aggregated Cu species) of ERI- and SSZ-13-based samples. View this paper
