Thinly sliced zeolites have greater catalytic activity! A common precursor gives ferrierite or, upon expansion and delamination, ITQ-6 (see picture). Delamination increases the external surface area and catalytic reactions with bulky molecules do not demand their permeation into the Angstrom-scale pores. The preparation also eases creation of even more active, titanium-enriched materials.
