ABSTRACT:
Pillared layered silicate compositions containing pillars of silica and metal oxides, e.g., alumina are prepared by contacting organic-swelled layered silicates, e.g. kenyaite-type materials, with a hydrolyzable silica precursor, e.g., tetraethylorthosilicate which forms silanol groups between the layers and contacting the resulting product with an aqueous solution containing inorganic metal salt and effecting hydrolysis of the silanol groups.
