▎ 摘　　要

NOVELTY - Preparing nickel-doped boehmite and reduced graphene oxide composite electrocatalyst, comprises dissolving formamide and water in a mixed solution, dissolving urea, dispersing graphene oxide uniformly, adding nickel nitrate hexahydrate and aluminum nitrate nonahydrates, and stirring uniformly, adjusting the pH value to 8-10, continuously hydrothermally reacting at 160-200degrees Celsius for 6-8 hours, cooling to room temperature, washing the obtained product, and drying. USE - The electrocatalyst is useful for reducing carbon dioxide into carbon monoxide (claimed). ADVANTAGE - The method is simple and provides catalyst having high catalytic activity. The electrocatalyst has large specific surface area and large conjugated structure, two surfaces of the sheet can be combined together to form a stable composite material by covalent bond with the metal hydroxide, increases the pore duct is good for the transmission of the substance, and has good conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nickel-doped boehmite.
