Abstract

Layered chalcogenide materials of high thermal stability and surface area which contain interspathic polymeric chalcogenides such as polymeric silica are prepared by ion exchanging a layered metal oxide, such as layered titanium oxide, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming a polymeric oxide, is thereafter introduced between the layers. The resulting product is treated to form polymeric oxide, e.g. by hydrolysis, to produce the layered oxide material. The resulting product may be employed as catalyst material in the conversion of organic compounds.
