Abstract
Carbon nanostructures are mass produced from graphite. In particularly preferred aspects, graphene is thermo-chemically derived from graphite and used in numerous compositions. In further preferred aspects, the graphene is re-shaped to form other nanostructures, including nanofractals, optionally branched open-ended SWNT, nanoloops, and nanoonions.
Claims8
A method of preparing a composition comprising a nanostructured carbon, the method comprising:
- contacting a carbonaceous starting material with an activated acid catalyst to form an activated intermediate;
- and
- providing thermal energy to the activated intermediate to thereby forming a graphene;
- wherein the activated acid catalyst comprises an acidic solution previously subjected to an electromagnetic field, electromagnetic radiation, laser irradiation, or plasma activation.
