▎ 摘　　要

NOVELTY - Preparing carbon material comprises providing a graphene oxide dispersion liquid of conductive particle intercalation, and granulating the graphene oxide dispersion liquid of the conductive particle intercalation to remove the solvent. USE - The method is useful for preparing carbon material, which is useful in catalyst carrier for preparing carbon nanotubes and their complex materials (all claimed). ADVANTAGE - The method: is economical; and obtains a carbon material with excellent loading performance in a simple, high specific surface area, excellent comprehensive properties that are not easy to agglomerate, and active surface, which greatly promotes the controllable preparation and wide application of carbon nanotubes. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a carbon material prepared by above mentioned method, which has a quasi-spherical or spherical structure, and the quasi-spherical or spherical structure is formed by agglomeration of carbon sheets composed of graphene oxide intercalated with multi-layer conductive particles; and a catalyst carrier, comprising the carbon material.
