Two-dimensional graphene-like molybdenum disulfide, a relatively new and exciting transition metal dichalcogenides, has a number of unique properties which have been widely studied. The structure, property and preparation methods of molybdenum disulfide are introduced in this paper in detail. In order to improve performance of molybdenum disulfide, some researchers start paying close attention to composite and decorating about molybdenum disulfide, such as graphene-MoS2, metal-MoS2, which is not mentioned in other review papers. In addition, we systematically review the application of molybdenum disulfide, which included field effect transistor, phototransistors, gas detector, digital logic transistors and biosensor. At last, we prospect for future advances in methods for preparing atomically thin layers and devices.
