In this work, the catalytic performance of clinoptilolite (CLIN) and SBA-15 catalysts, doped with Fe and Cu, was evaluated in the selective catalytic reduction of NO using NH3 as a reducing agent (SCR-NH3). Both Cu-CLIN and Fe-CLIN were obtained by ion-e
However, a slight shift in the position of the peaks towards larger angles gave grounds to assume that there was a partial incorporation of Fe into the crystalline zeolite structure, which led to the compression of the unit cell. Analysis of the SEM data (Figure 2) showed that both samples...
[1,2,3]. The H+from the OH group connected to the framework aluminum atom in zeolite can act as a proton donor, thus playing the role of a Brønsted acid site (BAS). The weaker acid sites dominantly come from non-framework aluminum and other balancing cations and act as Lewis acid ...
