Graphene nanoribbons, graphene nanoplatelets and mixtures thereof and synthetic methods

摘要

Graphene nanoribbons with high structural uniformity and low levels of impurities and methods for their synthesis are provided herein. Also provided herein are graphene nanoplatelets with superior structural uniformity and low levels of impurities and methods of their synthesis. Also provided herein is a mixture of graphene nanoribbons and graphene nanoplatelets with excellent structural uniformity and low levels of impurities and methods of their synthesis. The method includes, for example, depositing a catalyst on a constantly moving substrate, forming carbon nanotubes on the substrate, separating carbon nanotubes from the substrate, and collecting carbon nanotubes from the surface. And wherein the substrate moves through the deposition, formation, separation and collection steps continuously and sequentially. In addition, the treatment step converts the synthesized carbon nanotubes into graphene nanoribbons, graphene nanoplatelets and mixtures thereof.
