▎ 摘　　要

NOVELTY - Manufacture of graphene-based nano-metal compound array material involves mixing a carbon precursor and a metal salt comprising potassium chloride and zinc chloride, grinding, coating resultant slurry on a foamed nickel substrate, heat-treating, washing, obtaining graphite-carbon nanosheets, subjecting resultant to electrodeposition using a dilute nitrate solution at room temperature, obtaining graphite-based metal hydroxide, and heat-treating. The carbon precursor is a mixture of glucose, and melamine or 1-ethyl-3-methylimidazolium dicyandiamide. USE - Manufacture of graphene-based nano-metal compound array material used as battery material for metal-ion battery, metal-air battery and supercapacitor, and material for electrocatalytic reaction, oxidation-reduction reaction, and precipitation reaction (all claimed). ADVANTAGE - The method enables simple and non-toxic manufacture of graphene-based nano-metal compound array material having excellent conductivity, ion-transport property, stability, electrochemical catalytic activity and durability. DETAILED DESCRIPTION - Manufacture of graphene-based nano-metal compound array material involves mixing a carbon precursor and a metal salt comprising potassium chloride and zinc chloride, grinding, coating resultant slurry on a foamed nickel substrate, heat-treating resultant product in an inert atmosphere at 700-100 degrees C for 0.5 hour or more, washing using deionized water and ethanol, respectively, obtaining graphite-carbon nanosheets, subjecting resultant to electrodeposition using a dilute nitrate solution at room temperature for 6-60 hours, obtaining graphite-based metal hydroxide, and heat-treating resultant at 500 degrees C or less and heating rate of 2-15 degrees C/minute for 1-5 hours. The carbon precursor is a mixture of glucose, and melamine or 1-ethyl-3-methylimidazolium dicyandiamide.
