Method for intercalating organic-swelled layered metal chalcogenide with a polymeric chalcogenide by plural treatments with polymeric chalcogenide precursor

摘要

Organic-swelled layered metal chalcogenides, e.g., titanometallates or silicotitanates, are intercalated with polymeric chalcogenide by plural treatments with hydrolyzable, electrically neutral polymeric chalcogenide precursor, e.g., tetraethylorthosilicate, to provide products of improved surface area.
