摘要:: 二硫化钼(MoS2 )具有典型的层状结构，易于形成寡层MoS2 纳米片，具有丰富的光、电、催化性能，在光电信息与能源转换等领域有广泛应用潜力．采用含钼化工原料并通过湿化学、气相沉积等方法制备寡层MoS2 纳米片，继而构筑MoS2 纳米片基功能纳米复合材料，是目前国内外的研究热点;但是，以化工钼试剂为原料制备MoS2 纳米片的工艺路线长且不绿色．而辉钼矿是以层状MoS2 为主要组分的矿物，在我国储量大，是制备寡层MoS2 纳米材料的良好原料，因此，以经提纯处理的层状结构辉钼矿为直接原料，采用插层－剥离技术制备寡层MoS2 纳米片是一种低碳经济途径．

Abstract:: Molybdenum disulfide ( MoS2 ) with a typical layered structure easily forms few-layered MoS2 nanosheets，and has a wealth of optical，electrical and catalytic performance with wide application potentials in areas such as photo-electrical and energy conversion． The preparation of few-layered MoS2 nanocrystals and MoS2-based nanocomposites using molybdenum-containing chemicals as starting materials by wet-chemical and vapor-deposition methods are the cutting-edge focuses of recent research． However，the synthesis of MoS2 nanocrystals from chemical reagents with a long route is not low-carbon and environment friendly． Molybdenite is a typical layered mineral and composed of layered MoS2 units． The amount of molybdenite in China is huge and it is a green and low-carbon way to prepare few-layered MoS2 nanomaterials via the intercalation-exfoliation strategy using the purified molybdenite as the direct raw materials．
