【摘要】：以硫酸铜为铜源,细菌纤维素(BC)为碳源,通过原位还原和高温热解的方法制备了碳化细菌纤维素包裹铜纳米粒子(CBC/Cu)。利用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射仪(XRD)、X光电子能谱(XPS)、拉曼光谱仪(Raman)对结构和微观形貌进行了表征。用CBC/Cu修饰的玻碳电极作为工作电极,用循环伏安法测试对硝基苯酚在碱性水溶液中的电化学行为,与裸玻碳电极相比较,结果表明该修饰电极具有良好的电化学催化性、高稳定性和重现性。
[Abstract]:Copper nanoparticles coated with bacterial cellulose (CBC/Cu) were prepared by in-situ reduction and pyrolysis with copper sulfate as copper source and bacterial cellulose (BC) as carbon source. The structure and microstructure were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X), (TEM), X ray diffractometer (XRD), X), photoelectron spectroscopy (XRD), X), (XPS), Raman spectrometer (Raman). The electrochemical behavior of p-nitrophenol in alkaline aqueous solution was measured by cyclic voltammetry with CBC/Cu modified glassy carbon electrode as working electrode. Compared with bare glassy carbon electrode, the results showed that the modified electrode had good electrochemical catalytic activity. High stability and reproducibility.
