Molybdenum sulfide nanoparticles（ nano-MoS2） are widely applied in catalysis,lubrication,photoelectric materials,deep hydrodesulfurization of diesel oil and other fields because of its unique layered-structure and properties.The physical and chemical preparation methods for nano-MoS2 are introduced. The main preparation methods developed newly in recent years,for instance,chemical vapor deposition,hydrothermal/solvothermal method,precipitation method and precursor pyrolysis method,are discussed.This paper investigates the formation mechanism and performances of nano-MoS2 in shapes of wire/rod/tube,fullerene-like,ball-like,flower-like and other specific morphologies.The effect of metal doping on the surface active sites and properties of molybdenum sulfide are analyzed.Finally,the research progresses and applications of these MoS2 with specific morphologies and relating composite materials are prospected.
