摘　　要：以七钼酸铵、水合肼为原料,以N,N-二甲基甲酰胺(DMF)为溶剂,通过工艺简单的溶剂热法制备了片状纳米二硫化钼,并对其进行了形貌结构表征和性能研究.结果表明,通过溶剂热法制备出的片状二硫化钼具有超薄的纳米片层和较多的钼基表面缺陷,极大地优化了二硫化钼的结构.相对商业硫化钼而言,该材料在酸性电解液下具有更好的电化学析氢(HER)性能.通过这种形貌结构的筑造,极大地提高了二硫化钼作为析氢反应负极材料的导电性.Nano-sized molybdenum disulfide was prepared by solvothermal method using ammonium heptamolybdate and hydrazine hydrate as raw materials and N,N-dimethylformamide(DMF)as solvent.The morphology,structure and properties of nano-sized molybdenum disulfide were characterized.The results show that the sheet MoS2prepared by solvothermal method has ultrathin nanolamellae and more defects on the surface of Mo base,which greatly optimizes the structure of MoS2.Compared with commercial molybdenum sulfide,this material has better electrochemical hydrogen evolution(HER)performance in acidic electrolyte.The electrical conductivity of molybdenum disulfide as hydrogen evolution reactive anode material is greatly improved by the construction of this morphology structure.
