▎ 摘　　要

NOVELTY - Preparation of three-dimensional modified graphene filter involves taking foamed metal, washing with acid solution to remove surface impurities and oxide layer from foamed metal, mixing cobalt salt, nickel salt, graphene and water to obtain dipping reagent, immersing foamed metal in dipping reagent, drying foamed metal and heat-treating foamed metal to decompose cobalt salt and nickel salt supported on surface of foamed metal. USE - Preparation of three-dimensional modified graphene filter (claimed). ADVANTAGE - The method enables simple and environmentally-friendly preparation of three-dimensional modified graphene filter with large surface area and strong adsorption capacity.
