摘　　要：采用壳寡糖为软模板,通过低温水热法合成了球状纳米Ni0.85Se晶体,在500℃下灼烧50 min,转化为空心球状NiSe2晶体。通过透射电镜(TEM)、X射线衍射(XRD)、紫外-可见光谱(UV-vis)和荧光光谱(PL)等手段对产物进行了分析和表征,讨论了复合物的形成机理及反应条件对产物的影响。研究了产物的电化学性质。Ni0.ssSe Spherical nanocrystaline was synthesized by using Chitooligosaccharides as soft-template in a low-temperature hydrothermal process, the as-obtained product could then be transited to hollow spherical NiSe2 nanocrystaline at 500 ℃. Both products were characterized by transmission electron microscope （ TEM）, X-ray diffraction （ XRD）, ultraviolet （UV） analysis and photolumineseence （PL）. The form mechanism and conditions affected were also discussed. In addition, the electrochemical properties of the two products were studied.
