NOVELTY - Electrode in which S-doped GO is introduced into the active layer, and includes a screen Ti, an intermediate layer and an active layer, and S-doped GO is introduced into the active layer. USE - Electrode. ADVANTAGE - The electrode produces hydroxyl radicals with strong oxidizing ability to oxidize and degrade organic pollutants, which can save costs and avoid secondary pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an electrode, which involves using wire mesh Ti as a substrate and perform surface pretreatment, using absolute ethanol as a solvent, prepare a mixed solution of SnCl4.5H2O, SbCl3, Mn(NO3)3 and Ce(NO3)3, adjusting the solution to acidity, and preventing SnCl4.5H2O from being hydrolyzed, ultrasonically forming metal alkoxide in an ultrasonic instrument, and let it stand for use, using absolute ethanol as the solvent, prepare a mixed solution of SnCl4.5H2O, SbCl3 and LaCl3.7H2O, adjusting the solution to acidity, then sonicating the metal alkoxide in an ultrasonic instrument, and let it stand for use, separately taking anhydrous ethanol, add graphene oxide and benzyl disulfide and stir to obtain a uniform suspension, adding uniform suspension to the metal alkoxide and stirring again to obtain an active layer coating liquid, using the intermediate layer solution to coat and heat the processed screen Ti, and then use the coating active layer solution to coat and heat the screen Ti, Ti/Ce-Mn/SnO2-Sb-La-S-rGO electrode prepared by sol-gel and thermal oxidation method is obtained.
