Modified bentonite-derived materials as catalysts for selective catalytic reduction of nitrogen oxides
2019
In the last few years, cationic layered clays, including bentonites have been investigated as potential catalysts for SCR DeNO x systems. In this work, bentonite as the representative of layered clays was modified in order to obtain an alternative, low-cost NH 3 -SCR catalyst. Samples of raw clay were activated with HCl or HNO 3 , treated with C 2 H 2 O 4 and subsequently pillared with alumina by the ionexchange. Afterwards, the modified materials were impregnated with iron and copper. The
