Ti-pillared clays (Ti-PILCs) were synthesized from Na-montmorillinite. Cu-doped pillared clays were studied as catalysts for selective catalytic reduction (SCR) of NO by propylene. Cu/Ti-PILC showed high activity at relatively low temperatures. The method of copper loading influences the catalytic activity of the catalysts. The following catalysts were also prepared and studied: Fe/Ti - PILC, Ce/Ti - PILC, Zn/Ti - PILC, Co/Ti - PILC, Ag/Ti -PILC and Ni/Ti - PILC. N2 adsorption/desorption isotherms and pore size analysis were applied to study the influence of the pillaring process and Cu loading on the clay structure.
