SOLVO-THERMAL SYNTHESIS OF METAL CHALCOGENIDES AND ITS EMPLOYMENT

Solvo-thermal syntheses of metal chalcogenides have been overviewed. All three elements of S, Se and Te, have a tendency to catenate. This results not only in rings or chains of their several elemental forms, but also in the polychalcogenide Qn2-(Q=S, Se, Te, n=2-6) ions that can exist in solutions or in the solid-state in various sizes. Organic solvent is easy to reaction with precursor of transition metal to produce a complex canon in the solvo-thermal synthesis of metal chalcogenides. The technique can be employed in preparing a semiconductor film and using to prepare the catalyze carrier materials and relevant to many inportant processes, such as hydrodesulfurization of crude oil, hydrogenation of unsaturated and aromatic hydrocarbons, biosynthasis of metalloproteins, and even the hydrothermal conversion of metals to their binary chalcogenide minerals in nature.
