Compared with conventional molybdenum disulfide, the number of surface atoms in Nano molybdenum disulfide is significantly increased, and more sulfur vacancies are formed, which makes the catalytic activity and selectivity of Nano molybdenum disulfide higher. Nano molybdenum disulfide can be used as a highly active hydrogenation catalyst for heavy oil conversion and fuel oil refining. Nano molybdenum disulfide is used as a catalyst in the process of carbon monoxide methanation with high selectivity and reactivity. Nano molybdenum disulfide is also a catalyst for coal liquefaction.
When used in the petrochemical industry, Nano molybdenum disulfide is a good catalytic hydrodesulfurization catalyst. Nano molybdenum disulfide that meets different functional requirements can be prepared by different methods, such as molybdenum disulfide self-lubricating thin layer, molybdenum disulfide intercalation battery, molybdenum disulfide high-efficiency hydrodesulfurization catalyst, etc. As the particle size of MoS2 becomes smaller, the adhesion and coverage of molybdenum disulfide on the surface of the friction material are significantly improved, and the anti-wear and anti-friction properties of molybdenum disulfide are also doubled. The energy band difference of the ultra-fine Nano molybdenum disulfide thin layer is close to 1.78eV, which matches the energy of light, and has application prospects in photovoltaic cell materials.
