摘　　要：为了制得超细化的二硫化钼,采用LiCl剥离辉钼矿。在室温下,将一定量的二硫化钼加入到氯化锂水溶液中,经搅拌、超声振荡,得到有沉淀的溶液。经过滤、水洗、干燥,用XRD,SEM表征,结果表明二硫化钼的径厚比明显减小,层厚达到约19 nm。其原因可能是锂离子进入到MoS2的层间,撑开了二硫化钼层化学剥离所致。In this paper, nano-sized MoS2 is prepared by a chemical method with lithium chloride. Characterized by XRD and SEM technologies,the result confirmed that the resultant is still molybdenum disulfide, and it is about 19nm in size, much smaller than the pristine one. The reason why molybdenum disulfide can be chemically exfoliated is that Li^＋ can be inserted into the interlayers of molybdenum disulfide.
