The possibility of electrodepositing molybdenum sulfide films using molybdenum foil as the counterelectrode was studied using combinations of various reagents and nonaqueous solvents. PC, DMF, DMA and DMSO were used as nonaqueous solvents; LiClO₄, KClO₄ and TEAP as supporting electrolytes; and S, KSCN, NaSCN, Na₂S₂O₃ and (H₂N)CS as sulfide reagents. The films were cathodically electrodeposited at electrode potentials of from -2.80V to -2.95V at 80°C in DMF solvent containing LiClO₄ as the supporting electrolyte and KSCN as the sulfide reagent.
The structures of these films were revealed by X-ray diffraction to be Mo₂S₃ and amorphous material. The mechanical strength was low.
