中文摘要：

以三方相t-Se纳米管为模板,N2H4·H2O为还原剂的碱性溶液中室温合成硒化镍纳米管。产物分别用扫描电子显微镜（SEM）、X射线衍射仪（XRD）、X射线光电子能谱（XPS）等表征手段进行表征。利用循环伏安法研究了硒化镍纳米管在不同介质中的电化学行为,探讨了电解质对硒化镍纳米管电化学性质的影响。

英文摘要：

The NiSe2 nanotubes were synthesized at room temperature using t-Se nanotubes as a template and N2H4 ·H2O as a reductant in alkalescent solution. The structure of the NiSe2 nanotubes was characterized using scanning electron microscope （SEM）, X-ray powder diffraction （XRD） and X-ray photoelectronic spectroscopy （XPS）. The formation mechanism of NiSe2 nanotubes was investigated. The electrochemical property of NiSe2 nanotubes was researched by cyclic voltammetry method in different medium solution.
