NOVELTY - Preparation of the copper-reducing nickel-chromium-graphene clustered foam involves plating nickel using copper/self-assembled-reductive graphene cluster composite material as cathode, nickel plating where electrolyte solution is at 35-45 degrees C, chromium plating at 38-60 A/dm2 current density, electro-deposition for 1 to 20 seconds, cleaning in de-ionized water and then drying in cold air. USE - Preparation of the copper-reducing nickel-chromium-graphene clustered foam used in electrolytic cathodes. DETAILED DESCRIPTION - Preparation of the copper-reducing nickel-chromium-graphene clustered foam involves mixing 0.5-1.0 g cationic surface active agent with 1000 ml water, isopropyl alcohol and sodium citrate solution to form colloidal solution, stirring at room temperature for 10-60 minutes, adding 0.5-1.5 g reducing graphene, ultrasonic crushing for 1 hour, preparing polyacrylamide anion solution in de-ionized water, stirring at room temperature for 2-3 hours, ultrasonic foaming the copper into wax-removing water for 10 to 15 minutes, cleaning in deionized water, removing the surface oil, foaming copper potassium persulfate in sulfuric acid solution to etch for 1 to 10 minutes, cleaning in deionized water, then in isopropanol, drying to produce graphene clusters, plating nickel using the prepared foam copper/self-assembled-reductive graphene cluster composite material as cathode, nickel plating where electrolyte solution is at 35-45 degrees C, chromium plating at 38-60 A/dm2 current density, electro-deposition for 1 to 20 seconds, cleaning in de-ionized water and then drying in cold air. DESCRIPTION OF DRAWING(S) - The drawing is a graph of the SEM curve of the foam copper/reducing graphene cluster test (Drawing includes non-English language text).
