Abstract: In one aspect, the invention relates to a method of synthesizing a nannoparticle/porous graphene composite, including dispersing porous graphene structures into a solvent to form a dispersion of the porous graphene structures therein, adding precursors of nanoparticles into the dispersion of the porous graphene structures in the solvent to form a precursor mixture, and treating the precursor mixture to form a nannoparticle/porous graphene composite. The composite is formed such that the nanoparticles are uniformly distributed in pores of the graphene structures. The composite is very useful as electrode materials in electrochemical devices, in which efficient ions and electron transports are required.

Abstract: The present invention provides a series of new and useful synthetic carbon allotropes. The carbon allotropes contain at least two inner hexagonal rings of 6 carbon atoms, which are characterized by hybridized sp2 bonds, as commonly found in graphene structure. The inner hexagonal rings are located in a central position within the carbon allotropes and bonded to each other in various configurations. Surrounding the hexagonal rings are additional carbon atoms, characterized by sp3 hybridized bonding, found in diamond, and more specifically in hexagonal diamond, also known as Lonsdaleite. These surrounding Lonsdaleite structures are bonded to and surround the inner hexagonal rings and support them in a central position within the carbon allotropes.

Abstract: A new carbon allotrope is disclosed comprising an inner ring of 6 carbon atoms, which are characterized by hybridized sp2 bonds, as commonly found in graphite structure. Adamene further contains an outer ring of 12 outer carbon atoms which surround and are disposed in the same plane as the inner 6 carbon ring. The 12 carbons existing in the outer ring are characterized by sp3 hybridization, as seen in a diamond structure. The carbon allotrope additionally contains a ring of 12 carbon atoms disposed above or below the plane of the inner 6 carbon ring. These additional 12 carbons are characterized by sp3 hybridized bonding, found in diamond, and more specifically in hexagonal diamond, also known as Lonsdaleite.
