Synthesis of Bi_2−2xSb_2xS₃ (0 ≤ x ≤ 1) solid solutions from solventless thermolysis of metal xanthate precursors

Abstract

Tris(O-ethylxanthate)bismuth(iii) (1) and tris(O-ethylxanthate)antimony(iii) (2) were synthesized and used as precursors for the preparation of Bi2−2xSb2xS3 alloys (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) using melt reactions.

Synthesis of (Bi1−xSbx)2S3solid solutionsviathermal decomposition of bismuth and antimony piperidinedithiocarbamates

“…44,53 O'Brien et al synthesize Bi 2À2x Sb 2x S 3 solid solutions from solvent less thermolysis of metal xanthate precursors and showed a slight deviation from linearity in the energy band gap on Sb substitution due to stoichiometric variations in the synthesized solid solution. 54 The Raman spectra of the particles are shown in Fig. 11.…”

Synthesis and characterization of zinc di(O-2,2-dimethylpentan-3-yl dithiocarbonates) bearing pyridine or tetramethylethylenediamine coligands and investigation of their thermal conversion mechanisms towards nanocrystalline zinc sulfide

“…44,45 Additionally, by mixing different ratios of metal xanthates, doped metal sulfides with various transition metals can be resulted and several studies showed that such systems are very useful for controlling the optical, electrical and crystalline properties. [46][47][48] The metal xanthates are generally stable at room temperature and their decomposition typically occurs thermally via a mechanism known as Chugaev elimination. 24 However, it is also possible to decompose them chemically with the use of primary amines at room temperature 49 as well as photochemically with UV irradiation.…”

Direct solvent free synthesis of bare α-NiS, β-NiS and α-β-NiS composite as excellent electrocatalysts: Effect of self-capping on supercapacitance and overall water splitting activity

“…The method avoids the use of long chain capping ligands, and thus offers the possibility of synthesizing nanomaterials with abundant exposed active sites for enhanced electrocatalytic performance 43,44 . Various single source precursors such as metal thiolates, metal salts of dithiocarbamates, xanthates, thiocarboxylates and thiotetrazoles have been employed in the synthesis of a variety of nanostructured materials [45][46][47][48] . In this work, we have employed the solventless approach to synthesize nickel sulfide using nickel xanthate complexes as single source precursors.…”
