Molybdenum diselenide has a wide range of applications and has great development potential in the optoelectronic industry.

Molybdenum diselenide, an inorganic chemical, is a compound of rare metal molybdenum and non-metal selenium. It is also called molybdenum selenide. Its molecular formula is MoSe2. Its appearance is gray/gray-black powder crystal with a hexagonal crystal structure. It has semiconductor properties and a layered structure, and can be peeled off to obtain two-dimensional materials.

The preparation methods of molybdenum diselenide mainly include: direct synthesis method, using molybdenum and selenium as raw materials, mixing according to the molar ratio of 1:2, and reacting under high temperature conditions; chemical vapor deposition method, using molybdenum oxide and selenium as raw materials, In the presence of argon and hydrogen, it is grown on a silicon dioxide substrate or a silicon substrate; the thermal oxidation mechanical peeling method uses a thermal oxidation method on a silicon substrate to obtain a block product, and then uses a mechanical peeling method to peel it off.

Molybdenum diselenide has a special crystal structure, excellent structural rigidity, thermodynamic properties and optoelectronic properties. It can be used as a solid lubricant, photocatalyst, optoelectronic material, energy storage material, etc., and is widely used in transistors, diodes, light modulators, Photodetectors, microelectronics, optoelectronics, lithium-ion batteries, solar cells and other fields.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Molybdenum Diselenide Industry 2022-2026” released by the Industrial Research Center, Molybdenum diselenide has a layered structure and is easy to peel off single layers to obtain two-dimensional materials. Molybdenum diselenide two-dimensional material is a direct band gap semiconductor material with a photoelectric conversion efficiency higher than that of ordinary molybdenum diselenide. It has great development potential in the field of optoelectronic devices and is used in transistors, diodes, light modulators, photocatalysts, batteries and other fields. , the main research object is molybdenum diselenide two-dimensional material.

Industry analysts said that with the continuous advancement of semiconductor technology, the functional integration of integrated circuits continues to increase, and the size requirements continue to shrink, manufacturing Traditional materials for components can no longer meet the demand, and two-dimensional materials among nanomaterials have attracted attention. Two-dimensional materials have the characteristics of high carrier mobility, adjustable band gap and electron spin, and excellent electrical and optical properties. As one of the typical products of two-dimensional materials, molybdenum diselenide has great application value in the semiconductor field.

In the field of energy storage batteries and power batteries, lithium-ion batteries currently dominate. However, lithium resources are relatively scarce in nature, and there is an urgent need for alternative products. Potassium is abundant in nature, and its electrochemical properties are close to those of lithium. Therefore, potassium-ion batteries Having attention. Molybdenum diselenide is used in potassium-ion batteries to increase the diffusion rate of potassium ions and increase the theoretical capacity of the battery, so it has good application prospects.

In addition, molybdenum diselenide can also be used in the medical field and in optical cancer treatment. Optical cancer treatment methods have the advantages of low side effects, minimal invasiveness, and high treatment efficiency. They mainly use near-infrared light. Molybdenum diselenide can be used as a near-infrared light-responsive material. It has the characteristics of suitable band gap, excellent photothermal properties, and strong near-infrared light capture ability, and has the most development value.

Globally, the main molybdenum diselenide manufacturers include American Elements, American Thomas Swan, American 2D Semiconductors, British Ossila, Dutch HQ Graphene, China Tungsten Industry Group, Chinese Henan Kerui Chemical, etc.
