NOVELTY - The application of RGO-Ce/WO3 nanometre modified CF material prepared by dissolving tungstate in distilled water, stirring at room temperature of 20-25 degrees C for 10-30 minutes to obtain solution (A), adding cerium salt to absolute ethanol, stirring at room temperature of 20-25 degrees C for 10-30 minutes to obtain solution (B), mixing solution (A) and (B) to obtain solution (C), dissolving graphene oxide in distilled water, ultrasonically processing for 1-2 hours to form suspension to obtain solution (D), mixing solution (D) and (C), stirring for 10-30 minutes to obtain precursor solution, dripping 2-3 mol/L hydrochloric acid solution to precursor solution, stirring mixture 10-30 minutes, adding 3-5 mol/L ammonium sulfate solution, stirring for 10-30 minutes, pretreating carbon fibers, soaking pretreated carbon fibers into obtained solution for 10-30 minutes, calcining at 180 degrees C for 24 hours and cooling naturally to room temperature of 20-25 degrees C used as cathode in degradation of ciprofloxacin, is claimed. USE - Application of RGO-Ce/WO3 nanometre modified CF material used as cathode in degradation of ciprofloxacin. ADVANTAGE - The method uses reduced graphene oxide instead of carbon black, and does not use the binder PTFE, which can prevent the increase of the electron transfer resistance and the coverage of the exposed active sites on the surface.
