Electrolysis method of intercalation of layered transition metal dichalcogenides

A new method of intercalating organic Lewis bases, alkali hydroxides, Cu and Ag metals in to Group V layered dichalcogenide single crystals at room temperature is reported. It involves electrolytic reduction, in a suitable electrolysis cell, using the dichalcogenide as cathode and generation of the fresh intercalate species at the cathode surface. The organic intercalated complexes exhibit superconductivity like the parent dichalcogenides below 4.2°K. © 1974.
