二硫化钼纳米微粒的表面修饰及结构表征

Surfface Modification and Structure Characterization of MoS2 Nanoclusters

本文以二－十六烷基二硫代磷酸吡啶盐为修饰剂，制备了表面修饰ＭｏＳ２纳米微粒，并采用ＸＰＳ、ＦＴＩＲ、ＴＥＭ、ＸＲＤ等方法对其结构进行了表征．结果表明：所得到的ＭｏＳ２纳米微粒粒度均匀，平均粒径为１０ｎｍ，表面为二－十六烷基二硫代磷酸离子所修饰，在甲苯、氯仿、丙酮等有机溶剂中有良好的分散度．

Molgbdenum disulfide(MoS2)nanoclusters prepared by dialkyldithiophosphate ion modification are reported.The nanoelusters were characerized by XPS,FTIR,TEM,XRE.Results show that the MoS2nanoeluster is capped with a layer of dialkyldithiophosphate molecules,and can be dispersed in organic solvent such as toluene,Chloroform.acetone ete and hasgood chemical and physieal stability.
