Abstract
The microporosity of Al-pillared Li-montmorillonites with different layer charges obtained by thermal treatment at different temperatures was studied by nitrogen adsorption/desorption at -196 degreesC. A correlation was observed between the decreasing sorption capacity of samples derived from lithiated precursors heated at ever increasing temperature arid the increasing contribution of the collapsed pyrophyllite-like areas inactive in pillaring. The dominant micropore radius remained below 3.5x10(-1) nm for all pillared samples, showing that, contrary to the common belief, the layer charge reduction by Hofmann-Klemen effect fails to bring about substantial changes in the lateral interpillar distances.
