我们报告了快速、可扩展且经济的策略——微波辅助铜配合物转化路线，基于优先化学转化和结晶过程来制造高质量的 CuS 纳米管。以环境条件下形成的Cu络合物Cu(TU)Cl中心点0.5H(2)O（TU =硫脲）纳米线作为自牺牲模板，高产率合成了具有矩形横截面的均匀CuS纳米管。这些具有矩形横截面的 CuS 纳米管的直径可以通过改变化学反应参数（例如反应时间、温度和溶剂）来有效调节。此外，以Cu-EBT（EBT铬黑T）复合纳米棒为前驱体，还成功制备了均匀的锥状CuS纳米管。这些具有矩形横截面的纳米多孔 CuS 纳米管已被证实作为非酶葡萄糖传感器非常有效。 CuS纳米管修饰电极对葡萄糖的氧化表现出优异的电催化活性，并且对葡萄糖浓度变化具有良好的线性依赖性和高度敏感性。
We report the rapid, scalable and economical strategy-microwave-assisted Cu-complex transformation route to fabricate CuS nanotubes with high quality based on a preferential chemical transformation and crystallization process. With the Cu-complex Cu(TU)Cl center dot 0.5H(2)O (TU = thiourea) nanowires formed in ambient conditions as self-sacrificed template, uniform CuS nanotubes with rectangular cross-sections were synthesized in high yield. The diameter of these CuS nanotubes with rectangular cross-sections can be effectively tuned through changing chemical reaction parameters, such as reaction time, temperature, and solvent. Furthermore, uniform cone-like CuS nanotubes were also successfully prepared by adopting Cu-EBT (EBT eriochrome black T) complex nanorods as precursors. These nanoporous CuS nanotubes with rectangular cross-sections have been confirmed to be very effective as nonenzymatic glucose sensors. The CuS nanotube-modified electrode shows excellent electrocatalytic activity towards the oxidation of glucose and good linear dependence and high sensitively to glucose concentration change.
