Catalytic reduction of oxygen in various types of fuel cell research is of great significance. In this paper, tetraphenyl manganese, iron, cobalt nickel, porphyrin and tetraphenyl porphyrin chemically modified glassy carbon electrode. The stable electrochemical performance of tetraphenyl iron and cobalt porphyrin glassy carbon electrode was successfully prepared by adsorption method. The influence of various factors on the electrode preparation was studied in detail. The effects of the above-mentioned methods were studied by cyclic voltammetry and rotating disk electrode Electrode catalytic oxidation of oxygen on the reaction process, measured in different pH solution in
