Results obtained by IR and EPR spectroscopy show that treatment of mordenites with NH4F solution under mild conditions leads to the appearance of a large amount of strong Lewis-acid sites, presumably low-coordinate Si ions. These sites, which enhance the catalytic activity of the fluorinated zeolites, may be considered as alternative active sites in the transformation of alkylaromatics.
