专利摘要

在合成过程中,将三种关键化合物:0.5 mmol 钼酸铵 [(NH4)6Mo7O24.4H2O]、10 mmol 硫脲 (CH4N2S) 和 2.5 mmol 柠檬酸溶解在 80 mL 去离子水中,生成解决方案。该溶液经过软化学处理,包括在聚四氟乙烯高压釜中在 180°C 下加热 24 小时。这会产生单层二硫化钼 (2D-MoS2),沉积到预先清洁的钢基材上,然后进行清洗和干燥。合成过程包括成核和颗粒生长步骤,这些步骤受到浴温、pH 值和搅拌速率等因素的影响。采用 XRD、FTIR 和 SEM 等分析技术来确认所需纳米晶量子点的形成。摩擦学测量表明摩擦系数较低 (0.4),凸显了润滑剂的功效。这项研究产生了一种有前景、经济高效且无毒的 MoS2 润滑剂,适用于各种工业应用,包括太空探索和医疗机械。 ......

权利要求: , Claims:We claim:1. A method for producing of quantum dot nanocrystalline and lubricant mono layer molybdenum disulfide (2D-MoS 2) on different steel substrates by hydro thermal special soft chemical route process.2. A method of as claimed in claim 1 wherein the immersed steel substrate is electrically conducting as inert in the alkali solution.3. A method as claimed in of claim 3 wherein electrically conducting substrate is steel.4. A method as claimed in of claim 3 wherein electrically conducting substrate steel balls different sizes and plates etc.5. A method as claimed in of claim 1 wherein said molybdenum disulfide (2D-MoS2) is deposited to a thickness preferably of one to six micrometers.6. A method as claimed in of claim 1 wherein molybdenum disulfide (2D-MoS2) is deposited on the immersed substrates having diameters of steel balls from 0.5mm to 15 mm and plates surface area 1cm 27. A method as claimed in claim 1 wherein for formation of quantum dot nanocrystalline and lubricant mono layer, 0.5 mmol of ammonium molybdate [(NH 4 ) 6 Mo 7 O 24 .4H 2 O], 10 mmol of thiourea (CH 4 N 2 S), and 2.5 mmol of citric acid was dissolved in 80 mL of deionised (DI) water followed by stirring on a magnetic stirrer for about half an hour and. This soft chemical solution was poured into a Teflon autoclave and then heated to 180oC at constant pressure for 24 hours; further. The mono layer has been deposited on pre cleaned steel substrates at a constant pressure, bath temperature and alkaline p H respectively.
