Solid solutions of M_2−2xIn_2xS₃ (M = Bi or Sb) by solventless thermolysis

Abstract

Bismuth, antimony and indium xanthates have been synthesized and employed for the preparation of Bi–In–S and Sb–In–S solid solutions by solventless thermolysis.

Photoelectrochemical Water Splitting by In2S3/In2O3 Composite Nanopyramids

“…The crystallinity and the formation of the In 2 S 3 /In 2 O 3 composite are further investigated with the help of Raman analysis, and the data are shown in Figure c. In 2 S 3 /In 2 O 3 -B-5 shows prominent Raman peaks at 208, 302, and 308 cm –1 , which are due to the tetragonal phase of In 2 S 3 . , The peak at 302 cm –1 is associated with the symmetric stretching vibrating mode of InS 4 tetrahedra . The peaks located at 489 and 620 cm –1 depict the formation of In 2 O 3 .…”

Compositional engineering of metal-xanthate precursors toward (Bi1−xSbx)2S3 (0 ≤ x ≤ 0.05) films with enhanced room temperature thermoelectric performance

“…40 Similarly, significant success has been achieved using antimony/bismuth complexes of dithiocarbamates, 30,41 dithiophosphates, 42,43 and thiourea, 44,45 as single-source precursors to prepare chalcogenide semiconductors. We chose metal xanthate precursors to prepare Sb 2 S 3 43,46 and Bi 2 S 3 37,47 due to the low decomposition temperature of metal xanthate complexes (B150 1C), and the advantage of producing oxidefree metal sulfide products compared to dithiocarbamate complexes via Chugaev elimination 46,48,49 during thermolysis. Concisely, this approach is simple and can produce high-quality metal sulfide with a controlled composition.…”

Scalable synthesis of Cu–Sb–S phases from reactive melts of metal xanthates and effect of cationic manipulation on structural and optical properties

“…Materials Characterisation. The synthesized materials were characterized by similar techniques as used previously 41,42 . Briefly, elemental analysis and thermogravimetric analysis were performed in the micro-analytical laboratory of the University of Manchester.…”

“…Raman spectra were recorded using a Renishaw 1000 Synthesis of antimony(III) ethylxanthate, Sb[S 2 COEt] 3 . The precursor was synthesized by using similar method as reported previously 41,42 . Briefly, potassium ethylxanthate (8.0 g, 49.9 mmol) was dissolved in ethanol (150 mL), followed by a gradual addition of antimony(III) chloride (3.79 g, 16.6 mmol) solution in ethanol (50 mL), with constant stirring for one hour at room temperature.…”
