NOVELTY - A reduced graphene oxide-cerium oxide/porous polyaniline ternary composite electrode material preparing method involves mixing cerium nitrate solution with urea, adjusting pH value by adding ammonia solution, maintaining temperature and calcinating to obtain a cerium oxide, adding aniline solution, sulfuric acid and sodium dodecylbenzenesulfonate, mixing ultrasonically, adding adenosine triphosphate to sulfuric acid and carrying out polymerization reaction prepare a composite material of adenosine triphosphate /polyaniline, adding hydrofluoric acid to form porous polyaniline, preparing cerium oxide/porous polyaniline and graphene oxide dispersion separately, adding to glassy carbon electrode to obtain the finished product. USE - Method for preparing reduced graphene oxide-cerium oxide/porous polyaniline ternary composite electrode material. ADVANTAGE - The method enables preparing reduced graphene oxide-cerium oxide/porous polyaniline ternary composite electrode material is simple in manner.
