The main characteristics of bismuth sulfide powder

Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of bismuth sulfide, bismuth sulfide overview, bismuth sulfide application, bismuth sulfide suppliers, bismuth sulfide price.

Bismuth sulfide overview

Bismuth sulfide, chemical formula Bi2S3. Molecular weight 514.15. Brown-yellow powder or crystal. Specific gravity 7.39. 685 ℃ decomposition. Insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid. Sulfur or it is made by transferring hydrogen sulfide into a solution of bismuth salts. For the preparation of bismuth compounds. Bismuth sulfide is an important semiconductor material, and its application in optoelectronic components and thermoelectric devices has brought great convenience to mankind. Nano-bismuth sulfide makes its various properties more optimized. Since the properties of nanomaterials largely depend on the morphology of nanomaterials, it is of great significance to synthesize more bismuth sulfide nanostructures with special morphologies.

The main characteristics of bismuth sulfide powder

Bi2S3 has a special layered structure and weak bonds between layered units, leading to anisotropy of Bi2S3 growth and nucleation into tiny platelets in solvothermal and hydrothermal synthesis. Under lower temperature conditions, the crystal growth rate of the reactants is faster than the nucleation rate, which is favorable for the growth of Bi2S3 nanoflakes in solvents with high viscosity and high surface tension. Powders synthesized in high viscosity and high surface tension solvents distilled water and distilled water-ethylene glycol (2:1) favored the formation of nanosheet structures. The lower surface tension energy and viscosity between Bi2S3 and solvent DMF are beneficial to strengthen the chemical force between S-Bi bonds in the chain. According to the PBC crystal growth theory, the growth of Bi2S3 crystals is along the maximum force. The direction of the strong bond chain grows the fastest, eventually forming Bi2S3 nanorods.

Applications of Bismuth Sulphide

Bismuth sulfide has the advantages of environmental, photoconductivity, and nonlinear optical response. It is widely used in solar cells, photodiode arrays and infrared spectroscopy. It can also be used in the manufacture of other bismuth compounds, free-cutting steel additives and in the microelectronics industry. Bismuth sulfide powder can be used to prepare bismuth sulfide nanosheets, nanosheets and ultrathin films.

Bismuth sulfide powder is suitable for liquid chemical exfoliation to prepare Bi2S3 nanosheets and nanoparticles, which can form multilayer films at most.

Bismuth sulfide (Bi2S3) has a good band gap of 1.3 eV (near infrared light) and a large absorption coefficient. It can be used for solution processing thermoelectric devices, photodetectors, photosensitizers, solar cells and supercapacitors. Bi2S3 is also an interesting polymer nanoparticle solar cell candidate.
