China’s antimony ore resources are very rich, and its reserves have been proved to account for more than 70% of the world’s total reserves. The plutonium is mainly in the form of stibnite and pustonia, which needs to be applied after deep processing. In recent years, the annual output of plutonium in China has been More than 2,000 tons, accounting for more than 1/3 of the world’s total output, 60% of which is exported as primary bismuth ingots, and the output value is low. Therefore, it is urgent to increase the added value of bismuth products. Bismuth sulphide (Bi2 S3) is an important Semiconductor materials have potential applications in thermoelectric, electronic and optoelectronic devices and infrared spectroscopy. The band gap energy of barium sulfide at room temperature is 1.33 eV, which can be used to fabricate photoelectric converters, which are widely used in thermoelectric cooling processes. The strontium sulfide not only enables blue shift of the UV-visible absorption wavelength and the fluorescence emission wavelength, but also produces a nonlinear optical response, enhances the redox capability of the nanoparticles, and also has excellent photoelectrocatalytic properties in luminescent materials, nonlinear optics. Materials, photocatalytic materials, etc. have broad application prospects. In recent years, it has also been found that nano-rhodium sulphide is an excellent X-ray tomography (CT) The lens agent has unique advantages over the traditional iodine contrast agent. Among the currently reported methods for synthesizing strontium sulfide nanomaterials, solvothermal method and reflux method are the most common methods. People use solvothermal method to prepare High-purity, crystal-type strontium sulfide nanorods.
Our group has obtained high-crystal type strontium sulfide nanorods by the reflow heating method. The fifth phase of Qin Fan et al.: Microwave method for synthesizing strontium sulfide nanorods liquid method and synthesizing well-crystallized strontium sulfide nanorods. Zhao et al. The strontium sulfide nanofibers are produced by the hydrothermal method in a closed autoclave, and the products are easily aggregated. In the reflux heating method, the reaction system is unevenly heated, and the temperature of the system is also limited. Therefore, both methods have limitations. In recent years, the preparation of nanomaterials by microwave method has been paid more and more attention. Microwave heating has the characteristics of fast heating, uniform heating, no temperature gradient and no hysteresis, and it can simultaneously heat the surface of the sample and the internal reaction. The formation of nanomaterials has a promoting effect. At present, researchers have used microwave radiation to synthesize nanomaterials such as CeO2 [11], Fe2O3 and Bi2 S3. It has also been reported in the literature to prepare rod-shaped or thorn-like strontium sulfide nanomaterials by microwave method. However, no systematic research has been carried out, and the source of Bi2 S3 nanomaterials is certain. The degree is affected. The author’s previous research shows that under the same conditions, bismuth citrate is more favorable for the formation of strontium sulfide nanorods than other sources. This study uses bismuth citrate with linear polymer structure as the starting material. The strontium sulfide nanorods were synthesized by microwave heating and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Different surfactants and dosages were also discussed. The effect on the morphology and dispersion of nano-rulphide.
