▎ 摘　　要

NOVELTY - Preparing graphene attached plastic loaded gold-cobalt sodium borohydride electro-oxidation catalyst, comprises fixing alkaline-resistant double-sided adhesive tape on one side of plastic surface, coating graphene on other side of double-sided adhesive tape, applying compaction pressure on graphene, placing graphene-adhered plastic in aqueous solution (6 g cobalt nitrate and 1 g ammonium chloride), pre-activating at 1 V for 3 minutes, electrically depositing cobalt, placing graphene adhered plastic cobalt substrate in 0.8 mmol/ml gold chloride solution for 3-5 minutes. USE - The method is useful for preparing graphene attached plastic loaded gold-cobalt sodium borohydride electro-oxidation catalyst (claimed). DETAILED DESCRIPTION - Preparing graphene attached plastic loaded gold-cobalt sodium borohydride electro-oxidation catalyst, comprises fixing alkaline-resistant double-sided adhesive tape on one side of plastic surface, coating 10-15 mg.cm/2 graphene on other side of double-sided adhesive tape, applying compaction pressure on graphene at 4-8 MPa, placing graphene-adhered plastic in 1 l aqueous solution (6 g cobalt nitrate and 1 g ammonium chloride), pre-activating at 1 V for 3 minutes, electrically depositing cobalt at 1 V for 0.5-1 hour, placing graphene adhered plastic cobalt substrate in 0.8 mmol/ml gold chloride solution for 3-5 minutes.
