Parameters of Molybdenum Disulfide Powder for CAS 1317-33-5 Molybdenum disulfide
Molybdenum disulfide (MoS2), with the chemical formula MoS2 and the CAS number 1317-33-5, is a remarkable material that has gained significant attention in various industries due to its unique properties and diverse applications. This layered black solid is a transition metal dichalcogenide, composed of molybdenum atoms sandwiched between layers of sulfur atoms, forming a crystal structure known as the trigonal prismatic arrangement.
One of the most notable features of molybdenum disulfide is its exceptional thermal stability and chemical inertness. It can withstand high temperatures without undergoing significant degradation, making it an ideal component in high-temperature applications like heat exchangers, catalytic converters, and aerospace materials. Its resistance to oxidation also makes it suitable for use in corrosive environments.
Molybdenum disulfide is known for its lubricity, which is second only to graphite. When finely ground into a powder, it forms a self-lubricating layer when subjected to friction, reducing wear and tear in machinery and bearings. This property makes it widely used in the manufacturing of automotive parts, bearings, and electrical contacts.
In addition to its tribological properties, MoS2 possesses remarkable electronic conductivity, particularly in its thin film form. The material exhibits semiconducting behavior, with variable electrical conductivity depending on the number of layers and external stimuli like pressure or light exposure. This tunable electronic property makes it an attractive material for developing novel electronic devices, such as sensors, transistors, and optoelectronics.
Molybdenum disulfide is also gaining interest in the field of energy storage, specifically as a cathode material for lithium-ion batteries. Its large surface area and high capacity for lithium storage make it a promising candidate for next-generation rechargeable batteries, improving energy density and cycle life.
Moreover, MoS2 has shown potential in photocatalysis, where it can absorb light and convert it into chemical energy. This ability, coupled with its inherent redox properties, has led to its use in water purification, air purification, and environmental remediation processes.
The synthesis of molybdenum disulfide can be achieved through various methods, including mechanical exfoliation, chemical vapor deposition (CVD), and hydrothermal synthesis. Each method yields different particle sizes, shapes, and surface properties, allowing for customization of the material’s performance according to specific application requirements.
In conclusion, molybdenum disulfide is a versatile material with extraordinary properties that have a wide range of applications across numerous sectors. From its role as a high-performance lubricant to its emerging potential in energy storage and photocatalysis, MoS2 continues to be a subject of active research and development. As scientists and engineers continue to explore its capabilities, the future of this fascinating compound holds great promise for innovation and technological advancement.
