以V2O5和H2O2为原料,乙二胺为模板剂,采用溶胶凝胶法结合水热法制备了含有模板剂的超长氧化钒纳米线,利用傅里叶红外光谱仪、拉曼光谱仪和X射线衍射仪分析了材料的结构特征。采用扫描电子显微镜(SEM)对形貌进行了表征。采用不同温度对样品进行了热处理,并综合分析了热处理温度对材料形貌和结构的影响。从SEM测试结果可以看出,本文制备的V2O5纳米线的最长可达40μm。结果表明,通过300℃热处理即可成功去除有机模板剂,得到正交相V2O5纳米线。最后,用蓝电测试系统测试了V2O5纳米线的电化学性能。
V2O5 and H2O2 as raw materials, ethylenediamine as templating agent, using sol-gel method combined with hydrothermal method containing template long vanadium oxide nanowires, using Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray diffraction The instrument analyzed the structural characteristics of the material. Morphology was characterized by scanning electron microscopy (SEM). The samples were heat-treated at different temperatures, and the effects of heat treatment temperature on the morphology and structure of the samples were analyzed. As can be seen from the SEM test results, the longest V2O5 nanowire prepared in this paper can reach 40μm. The results show that the organic template can be successfully removed by heat treatment at 300 ℃ to obtain the orthorhombic V2O5 nanowires. Finally, the electrochemical performance of V2O5 nanowires was tested using a blue-electricity test system.
