Thio sol-gel synthesis of titanium disulfide from titanium thiolates.

2823 - 2826.
Titanium disulfide, TiS2, has been successfully prepared via a thio 'sol-gel' process using titanium(IV) thiolate precursors as the metal source. Four precursors have been investigated, namely [Ti(SBut)(4)], [Et2NH2][Ti-2(SCH2Ph)(9)], [Et2NH2][Ti(SC6F5)(4)(NEt2)] and [Et2NH2](3)[Ti(SC6F5)(5)][SC6F5](2). The titanium(IV) thiolate reacts at room temperature with H2S to form a precipitate which upon annealing at 800 degreesC under H2S results in the formation of crystalline TiS2. The TiS2 produced was analysed by powder X-ray diffraction, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA) and Raman spectroscopy. Annealing the precipitate obtained from the thio 'sol-gel' process at 600 degreesC under H2S results in the formation of a mixture of crystalline TiS2 and Ti1.25S2.
