[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.
