▎ 摘  要

NOVELTY - Synthesizing (M1) graphene nanoribbons, comprises: (a) continuously depositing catalyst on a constantly moving substrate; (b) forming carbon nanotubes on the substrate; (c) separating carbon nanotubes from the substrate; (d) collecting carbon nanotubes; and (e) converting the carbon nanotubes to graphene nanoribbons, where the substrate moves sequentially through the depositing, forming, separating, collecting and converting steps. USE - The methods are useful for synthesizing: graphene nanoribbons; a mixture of graphene nanoribbons and graphene nanoplatelets; and graphene nanoplatelets. ADVANTAGE - The method provides: the graphene nanoribbons with greater than 90%, 95%, 99%, 99.5% or 99.9% purity, the graphene nanoribbons and graphene nanoplatelets with greater than 90%, 95%, 99%, 99.5% or 99.9% graphitic carbon purity, and the graphene nanoplatelets with greater than 90%, 95%, 99%, 99.5% or 99.9% graphitic carbon purity; and high quality and inexpensive graphene nanoribbons and graphene nanoplatelets with high structural uniformity and purity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) synthesizing (M2) a mixture of graphene nanoribbons and graphene nanoplatelets, comprising the steps (a)-(d) as per se, and converting the carbon nanotubes to a mixture of graphene nanoribbons and graphene nanoplatelets; and (2) synthesizing (M3) graphene nanoplatelets, comprising the steps (a)-(d) as per se and converting the carbon nanotubes to graphene nanoplatelets, where the substrate moves sequentially through the depositing, forming, separating, collecting and converting steps.
