NOVELTY - Preparation of new boron graphene electrode involves obtaining a base sheet using iron, platinum, cobalt or conductive glass, placing the base sheet into a heating furnace, and pretreating by heating under argon protection, adding graphene and borazine to water, methanol, ethanol or isopropanol solvent, mixing to obtain a mixed solution of graphene and borabenzene, loading into the closed reaction chamber containing base sheet by capillary injection, reacting under argon gas, terminating addition of mixed solution of graphene and borabenzene, and cooling the electrode to room temperature. USE - Preparation of new boron graphene electrode used for treating sewage. ADVANTAGE - The method enables preparation of new boron graphene electrode using efficient and environmentally-friendly apparatus. The boron graphene electrode effectively reduces the chemical oxygen demand value and generation of nontoxic and harmful gases in sewage. DETAILED DESCRIPTION - Preparation of new boron graphene electrode used for treating sewage involves using iron, platinum, cobalt or conductive glass as a substrate, obtaining a base sheet by chemical vapor deposition method, placing the base sheet into a heating furnace, heating under argon protection for 4-6 hours, maintaining the reaction chamber of the furnace at constant temperature and constant flow rate of argon, adding graphene and borazine to water, methanol, ethanol and isopropanol solvent, mixing to obtain a mixed solution of graphene and borabenzene, controlling the mixed solution of graphene and borabenzene by a precision flow pump, loading into the closed reaction chamber by capillary injection, reacting under argon gas for 4-6 hours, terminating addition of mixed solution of graphene and borabenzene, turning off the furnace, maintaining the flow rate of argon unchanged, and cooling the electrode to room temperature.
