Molybdenum disulfide is a type of lamellar solid. Based on the exfoliation/restacking properties of LiMoS_2, several intercalation compounds of molybdenum disulfide with rich photic, electrical, magnetic, thermal and catalytical properties have been prepared. The preparation, structure, characterization methods,application and the ecfect of various intercalants on intercalation compounds are described in this paper.
