Title
Adsorption/desorption and catalytic oxidation of VOCs on montmorillonite and pillared clays
Abstract

In present work, adsorption/desorption and catalytic oxidation of three common volatile organic compounds on Na-montmorillonite, Al and AlCe pillared clays supported Pd catalysts, were investigated. The results showed that after pillaring, SBET, Vmicro and Vmeso of clays were obviously increased, which then improved the Pd dispersion. Catalysts with suitable amount and strength of acidity are fit for VOC adsorption and deep oxidation. VOC adsorption/desorption and catalytic activity results showed that catalysts with high SBET, large pore volume and suitable acidity can adsorb more VOCs, and exhibit better catalytic activity for VOC deep oxidation.

►After pillaring, SBET, Vmicro and Vmeso were obviously increased. ►Catalysts with large pore volume and suitable acidity can adsorb more VOCs. ►Pd/AlCe-PILC exhibits the highest adsorption capacity and catalytic activity.
