DETAILED DESCRIPTION - A nano- carboxylic acid/cobalt oxide graphene nano wall doped electrode manufacturing method involves preparing graphene nano wall by using carbon-containing gas as a precursor plasma, passing into the carrier gas, heating the substrate at 650-1000 degrees C in PECVD reactor by PECVD grown graphene nano-wall on the substrate, the precursor airflow of 10-100 sccm an atmospheric pressure of 10-100Pa, growth time control of 5-240 minutes to obtain a height 0.5 m 5-5 graphene nano-wall. Wall surface modified nano graphene is prepared at plasma power of 5-100W graphene nano wall bombarding for 30-300 seconds. 1-10 mass parts glacial acetic acid, citric acid, tartaric acid are dissolved in water and ethanol, concentrated hydrochloric acid to adjust pH to 3-6. 0.5-10 mass parts cobalt carbonate, cobalt chloride or cobalt acetate are utilized as a precursor, dissolved in a solution, sufficiently stirred at 60 degrees C to obtain a 0. 1-1 molL of cobalt precursor solution. 2-10 mass parts surfactant is mixed in the cobalt precursor solution followed by adding potassium hydroxide to adjust the pH to 8-12, sufficient stirring at 60 degrees C in a water bath to obtain 5-100nm (OH)2 sol nanoparticles, using modified graphene nano-wall / substrate as a negative electrode, a platinum plate as a positive electrode, and cobalt hydroxide as an electrolytic solution nanoparticles sol subjected to electrophoresis, the voltage set to 20-100V, current set to 5-100 mA, after electrophoresis for 30-300s, to obtain cobalt hydroxide nanoparticles adsorbed on graphene nano-wall, adsorbing onto nanowall graphene nanoparticles / substrate in the protective gas atmosphere in a heat treatment.
