NOVELTY - Preparing magnetic graphene by iron salt vapor phase intercalation and microwave technology comprises (i) intercalating the iron salt and natural flake graphite into natural flake graphite layers by vapor phase intercalation to obtain iron intercalation graphite intercalation compound, (ii) reducing the iron intercalated graphite intercalation compound obtained in step (i) to obtain nanometer iron intercalated graphite composite material i.e. nano-iron/graphite, and (iii) microwaving the nano-iron/graphite obtained in step (ii) to obtain final product. USE - The method is useful for preparing magnetic graphene by iron salt vapor phase intercalation and microwave technology. ADVANTAGE - The method: does not use strong acid or alkali; has low risk; and does not undergo reduction process of cerium oxide of graphene and thus the structure of graphene is not destroyed.
