▎ 摘　　要

NOVELTY - Manufacture of nanoporous graphene nanowires involves dissolving (110) a magnesium compound in water to form a solution having a magnesium ion concentration of 0.005-10.0 mol/L and treating the solution under hydrothermal synthesis to obtain catalysts, calcining (120) the catalysts at 100-800 degrees C to form porous catalyst nanowires, introducing (130) a carbon source to a reactor containing the porous catalyst nanowires at 400-1500 degrees C to grow graphene on the porous catalyst nanowires which in turn forms a composite, and obtaining (140) porous graphene nanowires from the composite. USE - Manufacture of nanoporous graphene nanowires used as electrochemical energy storage material, carriers of catalysts, conductive material, adsorption material and desorption material in articles, preferably electrode of battery (all claimed). ADVANTAGE - The method enables simple and efficient manufacture of nanoporous graphene nanowires in high yields.
