▎ 摘　　要

NOVELTY - A magnetic graphene and magnetic graphene oxide manufacturing method involves utilizing crystalline ordered graphite such as natural graphite, pyrolite graphite, chemical and physical modified graphite having crystalline structure (amorphous graphite is not appropriate), and electro-magneto-chemical process. USE - Method for manufacturing magnetic graphene and magnetic graphene oxide such as magnetic metal-doped multi-layered graphene that is utilized for electronic or electromagnetic applications, and removal of hydrocarbons from the surface of a spoiled liquid, and spill oil from water (all claimed), and in renewable energy application such as electrocatalysis in fuel cells, solar cells, lithium-ion batteries, supercapacitors, and flexible displays. ADVANTAGE - The method enables manufacturing magnetic graphene and magnetic graphene oxide with improved magnetic properties, high quality, high yield, better ability to exfoliate graphene continuously without interrupting the intercalation process, and high degree of crystallinity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a magnetic metal-doped multi-layered graphene (2) an use of magnetic graphene.
