At the same time, the electrochemical properties of BNMO thin films were studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results showed that the prepared BNMO thin film was a pure phase with a smooth surface and a dense microstructure. CV curves measured in the potential range of 0-1.2 V showed good redox peaks, indicating excellent electrochemical activity of the film. For the EIS test, the Nyquist plot of the BNMO thin film showed a sloping line and a small arc, indicating low charge transfer resistance and high electrode surface reaction rate. Therefore, the results of this study show that the preparation of BNMO thin film is feasible and has good electrochemical properties, and it is expected to be applied in some new electrochemical devices.精品文档---下载后可任意编辑Keywords: BNMO thin film; preparation; electrochemical performance; polarization curve; impedance spectrum.
