[0025] This example illustrates the method and characterization method of the iron phthalocyanine doped electrode provided by the present invention. The steps of doping iron phthalocyanine to filter cathode membrane are as follows:
[0026] (1) Dissolve polyimide and polymethyl methacrylate, a film-forming hydrophilic modifier, in dichloromethane solution at a temperature of 35°C, wrap them in tin foil, stir for 7 hours in the dark, and let stand for 8 hours to obtain Homogeneous solution free of air bubbles. The mass ratio of described polyimide and film-forming hydrophilic modifier is 2.5:1, and the mass ratio of described polyimide and dichloromethane is 1:7;
[0027] (2) Mix activated carbon, conductive material carbon nanotubes, and iron phthalocyanine at a mass ratio of 12:2:1, and mix the mixed material with the homogeneous solution that has been debubbled in (1) at a mass ratio of 7:1 Ultrasound for 40 minutes to make conductive film liquid;
[0028] (3) According t...
