Abstract
Microporous materials of low acidity useful as sorbents and catalytic supports have been produced by pillaring tetrasilicic mica with silica polyoxocations generated by hydrolysis of organosilane precursors. Calcination at an intermediate temperature followed by washing of the solid with water is important in producing highly microporous material.
