▎ 摘　　要

NOVELTY - A graphene loaded nano-nickel catalyst for composite carbon nanotube, comprises (in mass %) nickel (1-10), where the particle diameter is 5-10 nanometer. USE - Graphene nano-nickel catalyst for composite carbon nanotube. ADVANTAGE - The graphene nano-nickel catalyst has high catalytic activity, prolonged service life, and is uniformly dispersed in the carrier of graphene. The catalyst is prepared in a simple and cost-effective manner with easy operation. The catalyst comprises the carrier having high intensity, large surface area and stable graphite alkene structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene nano-nickel catalyst.
