ABSTRACT:
There is provided a method for pillaring a layered silicate, such as kenyaite, with polymeric oxide by using a single step treatment with a mixture of swelling agent and pillar precursor. The swelling agent may be an organic cation, such as a cetyltrimethylammonium cation, and the pillar precursor may be a compound which is capable of hydrolyzing to form a polymeric oxide. Tetraethylorthosilicate is an example of such a pillar precursor.
