Synthesis of kenyaite-type layered silicate material and its polymeric chalcogenide intercalates

摘要

An improved, economical and reproducible method for preparing synthetic Kenyaite-type layered crystalline silicate exhibiting high crystallinity and purity, catalytic utility and other valuable properties is provided. The method comprises forming a reaction mixture containing a source of alkali metal cations, organic agent, a source of silicon, a source of non-alkali metal, optionally aluminum, and water. The pillared layered crystalline silicate is also provided.
