A simple technique is presented for the production of films of transition metal disulfides such as MoS 2 , WS 2 , FeS 2 , or RuS 2 by the reaction of transition metal carbonyls (e.g. Mo(CO) 6 , W(CO) 6 , Fe(CO) 5 , Ru 3 (CO) 12 ) with a sulfur source (e.g. S, H 2 S) in an organic solvent (e.g. benzene, toluene, xylene, mesitylene (1,3,5-trimethyl-benzene)) at temperatures ranging between 80 to 165 °C. The quality of the materials and films has been investigated and some applications are discussed. They include use of the chemically prepared sulfides as photoactive materials (e.g. MoS 2 , WS 2 , FeS 2 ), as lubricating films (MoS 2 ), as electrodes for Li-batteries (MoS 2 , FeS 2 ) and for corrosion protection (RuS 2 ). |
