The invention discloses a preparation method of a graphite-based cerium-doped beta-PbO2 electrode and application of the graphite-based cerium-doped beta-PbO2 electrode. The graphite-based cerium-doped beta-PbO2 electrode is obtained by taking graphite as an anode and directly electroplating cerium-doped beta-PbO2 on graphite; components of electroplating liquid comprise 0.5-0.6mol/L of Pb(NO3)2, 0.2-0.8mol/L of Cu(NO3)2, 0.05-0.1mol/L of HNO3 and 0.002-0.008mol/L of Ce(NO3)3 and the balance being water; and in an electroplating process, the current density is 20-30MA/cm<2>, the temperature of the electroplating liquid is 70-85 DEG C and the electroplating time is 6-8 hours. According to the method, the production cost is low and the production process is simple; and a beta-PbO2 active layer with small grain sizes can be obtained by doping cerium into the electroplating liquid. The electrode is used as a working electrode to detect COD and can be used for rapidly, simply and accurately detecting the COD in water; and the detection efficiency can be effectively improved.
