| Abstract: | PbO_2electrodes modified with different concentrations of polyvinylpyrrolidone(PVP) were prepared using electrodeposition method.The microstructure and electrochemical properties of the modified electrode were investigated using SEM,XRD,electrochemical impedance spectroscopy(EIS) and liner sweep voltammetry(VA) techniques.Results show that PVP molecules can be coated around PbO_2 particles and can restrict their further growth and polymerization,which lead to a uniform and fine crystalline grains.The modifi... |
