Abstract

The invention provides a preparation method of an Sb2S3 nanowire. 10 mmol of Sb2Cl3 is dissolved into 2 ml of glycol; after the Sb2Cl3 is totally dissolved, 10 ml of deionized water is added while stirring to form white emulsion A; 15 mmol of Na2S.9H2O is dissolved into 10 ml of deionized water to form solution B; the solution B is added into the solution A at the rate of 2 drips/ second to form a precursor; mineralizer is added into the precursor to prepare 30 ml of solution C, and the solution C is put in an agitated reactor; the agitated reactor is put into an incubator; when temperature rises to 240 DEG C, temperature is kept for 8-16 hours; and after reaction ends, the product is washed by deionized water to be neutral and is dried for 4h in vacuum in the incubator of 80 DEG C. The invention has simple preparation method, short reaction period and low cost.

Description

【Technical Field】 [0001] The present invention relates to a nano Sb 2 S 3 The preparation method of the material, especially a kind of Sb 2 S 3 Preparation method of nanowires. 【Background technique】 [0002] Antimony sulfide (Sb 2 S 3 ) Is an important direct band gap inorganic semiconductor material for V-VI, with an orthorhombic crystal structure and a band gap energy of 1.72 eV at room temperature. Due to its high photosensitivity and thermoelectric properties, antimony sulfide is considered an ideal material for solar energy. In addition, antimony sulfide is also considered to be widely used in infrared field, thermoelectric cooling technology and optoelectronic technology. [0003] In recent years, many researchers have used chemical vapor deposition (CVD), template method, evaporation condensation method, and hydrothermal (solvothermal) method to prepare antimony sulfide crystal phases with various morphologies. For example: Hu H M, Mo M S, YangB J, etc. (Solvothermal synt...
