Problems solved by technology

However, during the hydrothermal preparation of the above-mentioned antimony sulfide one-dimensional materials, a thermal decomposition precursor needs to be synthesized in advance, which brings inconvenience to the synthesis.
In addition, there is no report on the growth of antimony sulfide nano-micron wire arrays on substrates by hydrothermal method.

Abstract

The invention discloses a preparing method of antimony sulphate nanometer-micrometer line and array, which comprises the following steps: weighing potassium antimony tartrate, dihydrate citric acid trisodium, thiomalic acid at 10:11:1-60 molecular proportion; stirring these raw materials in the secondary distilled water sequently; loading the composition in the polytetrafluoroethylene liner of stainless steel high-pressure autoclave to seal; reacting at 140-240 deg.c for 3-24 h to obtain the product. The beam-shaped antimony sulphate nanometer-micrometer line and array can grow on the surface of substrate with ITO glass, tungsten filament or SiN micrometer fiber in the polytetrafluoroethylene liner simultaneously, which possesses excellent single-crystal structure.

Description

technical field [0001] The invention relates to a preparation method of antimony sulfide nano-micro wire and array thereof. Background technique [0002] One-dimensional nano-micron materials have been extensively studied due to their unique optical, electrical, and thermal properties, and show potential applications in nanodevices. There are many synthetic methods for one-dimensional nano-micron materials, among which hydrothermal method and solvothermal method are very effective synthetic methods. The hydrothermal method and the solvothermal method generally react in an autoclave. The difference between the hydrothermal method and the solvothermal method is only that the former uses water as a solvent, while the latter uses a non-aqueous organic compound as a reaction medium. The reaction solution needs to be contained in the polytetrafluoroethylene lining of the stainless steel autoclave, and then the stainless steel autoclave is sealed and placed in an oven at a tempera...
