摘　　要：采用水热法合成ZnS纳米晶,对其反应动力学进行了研究。利用XRD、TEM等手段对样品进行了表征。在150℃反应时间为10h下,用水热法制备ZnS纳米晶,平均粒径在17nm左右,所得样品为闪锌矿结构,立方晶系,形貌为球形。动力学研究表明,ZnS纳米晶粒径随反应时间呈线性增加,ZnS纳米晶的平均生成活化能为27.44 kJ.mol-1。The reaction kinetics of ZnS Nano crystallites synthesized by hydrothermal method is studied.The samples are characterized by XRD,TEM and other means.Under the condition of the temperature is 150 ℃ and the reaction time is 10h,ZnS Nano crystallites is synthesized by hydrothermal method.The samples have a spherical morphology,the Zinc-blende structure and their average particle size is about 17nm.They belong to cubic system.Kinetic studies show that,the particle size of ZnS Nano crystallites increased linearly with reaction time,and the average generative and activation capacity of Nano crystallites is 27.44 kJ·mol-1.
