RF plasma assisted preparation of transition metal sulfides

The authors discuss their study of the low temperature preparation of transition metal sulfides. They are specifically interested in these sulfides for their use in both secondary batteries and as catalytic materials. The production of sulfide powders from the metal and sulfur can be difficult, this is particularly true for TiS2, VS2 and MoS3j. In the case of TiS2 titanium metal is quite inert to sulfur until temperatures of at least 6000C are obtained. Even at this temperature, probably a consequence of oxide layer formation, the reaction proceeds slowly and usually requires several days before completion. They felt that the use of a plasma assisted process could allow the less costly production of TiS2 from H2S at low thermal temperatures
