Effect of Preparation Methods on Ti-PILCs Catalysts in Selective Catalytic Reduction of NO by Propylene

Abstract:

Different Cu-loading pillared clays catalysts were studied in selective catalytic reduction of NO by propylene. The catalyst prepared by incipient wetness impregnation (Cu/Ti-PILCs) had better catalytic activity and stability than that prepared by ion-exchanged method (Cu-Ti-PILCs). Cu/Ti-PILCs has higher BET surface area than Cu-Ti-PILCs. Pore size distribution analysis and XRD showed that Cu species dispersed well in Cu/Ti-PILCs but formed conglomeration in Cu-Ti-PILCs. TPR showed that Cu²⁺ species were the main active species on the Cu/Ti-PILCs, which was responsible for the high catalytic activity of catalyst.
