Abstract
A material of porous graphene nanowires with a pore-rich structure is formed by synthesis of catalyst nanowires for porous graphene nanowires, chemical vapor deposition of a carbon source on the catalysts to grow graphene, removal of residual catalyst, and formation of the porous graphene nanowires. The porous graphene nanowires can be used as an electrochemical energy storage material, carriers of catalysts, a conductive material, an adsorption material, a desorption material, or the like.
Claims18
A material, comprising nanoporous graphene nanowires, wherein the nanoporous graphene nanowires are formed by:
- dissolving a magnesium compound into water to form a solution having a concentration of magnesium ions in a range of about 0.005-10.0 mol/L, and treating the solution to obtain catalysts;
- calcining the catalysts at a temperature in a range of about 100-800° C. to form porous catalyst nanowires;
- introducing a carbon source to a reactor containing the porous catalyst nanowires at a temperature in a range of about 400-1500° C. to grow graphene on the porous catalyst nanowires, thereby forming a composite thereof;
- and
- obtaining the porous graphene nanowires from the formed composite.
