These novel nanocomposites are microporous nanometal intercalated clays which have been prepared by a polyol process at 200C and a novel microwave-hydrothermal process using ethylene glycol. These novel nanocomposites have been found to be useful in the conversion of coal to asphaltenes. A crystalline tin (IV) arsenate hydroxide hydrate has been made and its lithium selective ion exchange properties have been measured. This exchanger has shown high lithium selectivity. Selective exchange of divalent transition metal ions in cryptomelane-type manganic acid with tunnel structure have also been studied. Several pillared clays have also been synthesized and their Mg[sup 2+], Li[sup +] and UO[sub 2][sup 2+] selectivity has been measured. The pillared clays appear to show some Li selectivity.
