The invention discloses a method for preparing a heterogeneous electric Fenton cathode material. The method comprises the following steps: with a single-room proton exchange membrane fuel cell as a reactor at room temperature, an air electrode employing platinum carbon as a catalyst as a cathode, a carbon material as an anode of the battery, a NaCl solution as electrolyte and NaHCO3 as a buffer agent, adjusting the pH value of the electrolyte to 5-8, adding a newly prepared ferrous salt solution after introducing nitrogen to remove oxygen, and then sealing the reactor; connecting the cathode and the anode of the battery by a lead connected with an external resistor of 0.01-1 kohm; detecting the voltage at two ends of the external resistor in real time; and when the voltage at two ends of the external resistor is reduced to zero, taking out the anode material and washing by distilled water until no chloride ion exists in the lotion, and then drying and carrying out heat treatment, thereby ...
