molybdenumbased

Molybdenumbased refers to compounds, alloys, and materials that contain molybdenum (Mo) as a principal element. As a transition metal with a high melting point, good corrosion resistance, and versatile chemistry, molybdenum strengthens alloys and participates in catalytic and electronic applications. The category encompasses a wide range of chemical classes and structural forms, including oxides, sulfides, carbides, nitrides, borides, and layered compounds, as well as metal alloys in which molybdenum is a major component.

Common molybdenum-based materials include oxides such as molybdenum trioxide (MoO3) and MoO2; sulfides such as molybdenum disulfide (MoS2) and related compounds; carbides (Mo2C); nitrides (MoN); and borides (MoB2). Layered compounds like MoS2 are studied for lubrication and as two-dimensional semiconductors. Molybdenum is also used in alloys, notably in stainless steel grades that contain molybdenum to improve strength and corrosion resistance at high temperatures.

Industrial relevance: Mo-based catalysts are central to hydrodesulfurization and hydrocracking in petroleum refining; MoS2-based catalysts are active in hydrogen evolution and other electrochemical reactions. In electronics and optoelectronics, layered molybdenum compounds serve as lubricants, dielectric layers, or two-dimensional semiconductors in transistors and sensors.

Natural occurrence and production: Molybdenum occurs mainly in the mineral molybdenite (MoS2). Commercial molybdenum is produced by processing molybdenite concentrates into MoO3, which can be used to furnish other Mo compounds or metal. Environmental and health considerations apply to several molybdenum compounds, requiring proper handling and regulatory controls during mining, refining, and industrial use.
