Montmorillonites, pillared with Al2O3 or TiO2, were modified by introduction of transition metal (Cu or Co) by ion exchange method. Pillaring of clay with alumina caused significant increase of surface area and micropore volume due to increase of interlayer distance. Modification of montmorillonite with titania also resulted in increase of surface area and porosity, however pillared material was characterized by delaminated structure. Additionally, part of TiO2 was deposited on the sample surface in form of separate phase. Among the studied catalysts, titania pillared montmorillonites modified with copper have shown the highest activity in reduction of NO with ethylene in flue gas purifn.
