Abstract
Due to the unique structural features, natural layered clay (bentonite) and synthetic layered zeolite (MCM-36) are very promising precursors of novel catalysts of selective catalytic reduction of nitrogen oxides with ammonia (NH3-SCR). Nevertheless, it is still unclear if the better option is to use cheaper material, abundant in the environment, with some contaminations or absolutely pure, but significantly moreexpensive one. Here we present the preparation, characterization, and comparison of the catalytic performance of bentonite and MCM-36 impregnated with copper in NH3-SCR. We have presented that the activity of the materials was influenced both by the applied catalyst support and the temperature of the reaction: Cu-modified bentonite exhibited higher activity above 350 ºC, while Cu-modified MCM-36 below that value. The effect was correlated with the deposition of bulk copper oxide species in the channels and pores of MCM-36, which were responsible for the side reaction of ammonia oxidation and its consumption during the catalytic process. In contrast, in the case of the catalyst supported on bentonite, no similar phenomena were observed. The results reported here confirm that there is a significant correlation between the form of the active sites, the catalyst support, and the catalytic performance.
