The fitting results show that, due to the large overpotential on the electrode surface, the electrode reaction is in the strongly polarized region at the current density greater than 1 mA•cm-2, indicating that it is of great significance to further improve the catalytic activity and reduce the overpotential generated by hydrogen peroxide to improve the performance of the electrode. In Fig.4h and i, the simulation results show that with the increase of current density, although the overpotential caused by various polarization processes increases, the potential required to maintain the high current of the electrolyte in the device grows fastest. This means that when preparing hydrogen peroxide industrially, it is necessary to design a reasonable electrochemical reaction device, and optimize the process parameters, and minimize the energy loss caused by the ohmic polarization of the electrolyte, which is the main factor affecting the energy efficiency of hydrogen peroxide industrially.
