【摘要】 以三氧化钼（MoO₃）为钼源，硫氰化钾（KSCN）为硫源，同时作为反应中的还原剂，采用相对温和的水热法制备微观形貌为花球状的二硫化钼（MoS₂），通过控制反应温度、反应物配比中KSCN物质的量，改变反应体系pH值，在反应体系中添加表面活性剂十六烷基三甲基溴化铵（CTAB）等，探索不同实验参数对产物MoS₂晶体结构和微观形貌的影响，实现合成过程中MoS₂形貌和尺寸的有效调控.实验结果表明，水热反应温度为240℃、pH值为0.6时是该反应体系制备花球状MoS₂的最适反应条件；且随着反应物KSCN的过量，所得MoS₂晶粒尺寸越来越小，表面片层间距也逐渐增大；添加了表面活性剂CTAB的产物形貌更加规整，尺寸更加均匀.更多还原

【Abstract】 MoO₃ and KSCN were taken as precursors to synthesize spherical flower-like MoS₂ through the hydrothermal method,where MoO₃ worked as the source of molybdenum for the reaction,and KSCN provided sulfur,KSCN also worked as the reducing agent of this reaction.With the method of controlling the reaction temperature,changing pH,adding a surfactant,and a large excess of sulfur source in the reagent,many experiments were explored to discover the effects of different experiment parameters on the crystal structure and morphology of MoS₂.The optimal conditions of the reaction to obtain the spherical flower-like MoS₂ were at 240 ℃,and the pH value is 0.6.Besides,with an excess of KSCN,the size of the MoS₂ became smaller and the intervals between the surface sheets also increased.After adding the CTAB,the morphologies of the products became more structured and their sizes became more uniform.更多还原
