Synthesis of CuSbS2 by the oil – water mixing solvothermal reaction
Abstract
Three element metal chalcogenide has special physical and chemical properties on semiconductor materials, catalyst carrier, solid chemistry, electromagnetic  and optical properties and it has irreplaceable importance in these high-tech fields. Their synthesis has become a very active research field of  inorganic synthetic chemistry now . This experiment adopts  the oil – water mixing solvothermal reaction as the preparation  of cusbs2 , discusses the influence of  different  precursor on cusbs2 preparation; Discussed within sodium diethyl dithiocarbamate preparation of precursor, the influence of different solvents, different water oil ratio and different temperature factors on cusbs2, using X-ray diffraction (XRD) and  scanning electron microscopy (SEM) to  cusbs2 for  being characterized. Results showed that   the optimum of oil - water mixed solvent thermal process for synthesis of cusbs2: apply reagent DDTC as the preparation of the precursor , liquid paraffin as organic solvent, water and paraffin ratio is 1:3, the reaction under 200 ℃ for 12 hours. Try reach a conclusion about the optimum condition of Synthesis of CuSbS2 by theoil-watermixing solvothermal reaction.

Key words: copper antimony sulfur; semiconductor materials; the oil – water mixing solvothermal; Solvent heat.
