NOVEL NANOCARBON CRYSTAL

摘要

The invention relates to the field of carbon material preparation. Disclosed is a novel nanocarbon crystal having an average particle diameter R and containing 99-100% of carbon. R satisfies the following condition: 0 < R ≤ 10 nm. The carbon crystal has a quasi-spherical shape. A surface carbon atom of the carbon crystal and a carbon atom in a diamond phase on an inner layer of the carbon crystal constitute a carbon atom dimer structure. The two carbon atoms of the carbon atom dimer structure are in an asymmetric arrangement. The novel nanocarbon crystal product has high crystallinity, surface activity and adsorbability, is of a regular and controllable shape, and has a loss rate controlled to be within 1%, can absorb full-spectrum solar energy, and a surface carbon atom thereof has high activity.
