【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。更多还原

【Abstract】 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 Ni Se2 nanotubes was researched by cyclic voltammetry method in different medium solution.更多还原
