Parameters of MoS2 powder CAS 1317-33-5 molybdenum sulfide powder
Molybdenum disulfide (MoS2) is a fascinating inorganic compound with the chemical formula MoS2 and the CAS number 1317-33-5. This compound, which consists of molybdenum atoms covalently bonded to sulfur atoms, has garnered significant attention due to its unique properties and versatile applications.
Firstly, MoS2 is known for its layered structure, forming a two-dimensional crystal lattice, often referred to as molybdenum disulfide nanosheets or graphene-like material. Each layer is composed of hexagonal arrays of molybdenum atoms sandwiched between layers of sulfur atoms. This atomic arrangement gives MoS2 exceptional mechanical strength, thermal stability, and high electrical conductivity.
One of the most striking features of MoS2 is its optical properties. It exhibits strong absorption in the visible and near-infrared regions, making it an attractive material for optoelectronic devices such as photodetectors, solar cells, and light-emitting diodes. Additionally, MoS2’s tunable bandgap, ranging from indirect to direct depending on the thickness, allows for the manipulation of its electronic properties for various applications.
In terms of chemistry, MoS2 is relatively inert under normal conditions but can be transformed into different forms through chemical reactions. It serves as a catalyst in several chemical processes, including hydrogenation, desulfurization, and oxidation reactions, due to its high surface area and active sites. The use of MoS2 as a catalyst is particularly relevant in the automotive industry, where it helps reduce emissions by converting harmful sulfur compounds into less harmful substances.
Another intriguing aspect of MoS2 is its superconducting properties. Under certain conditions, it exhibits unconventional superconductivity, meaning it can conduct electricity without resistance at very low temperatures. This property holds promise for potential applications in high-speed data transmission and energy storage systems.
In the field of energy storage, MoS2 finds application in lithium-ion batteries as anode materials. Its large theoretical capacity and high electronic conductivity make it an ideal candidate for enhancing battery performance. Furthermore, MoS2 is being investigated for use in supercapacitors, where its fast charge-discharge capabilities and high surface area contribute to efficient energy storage.
Biomedical applications of MoS2 are also emerging. Due to its biocompatibility and non-toxic nature, it is explored as a material for drug delivery systems, tissue engineering scaffolds, and even as a biosensor for detecting biomolecules. Its ability to modulate cell adhesion and proliferation makes it a promising candidate for regenerative medicine.
In summary, molybdenum disulfide (CAS 1317-33-5) is a multifaceted material with extraordinary properties that span across various industries. Its layered structure, optical, chemical, and electronic characteristics make it a valuable component in applications ranging from electronics to energy storage, catalysis, and even biology. As research continues to unravel its full potential, MoS2 is poised to play a pivotal role in shaping the technological landscape of the future.
