Synthesis of metal-incorporated graphitic microporous carbon terminated with highly-ordered graphene walls-Controlling the number of graphene layers by ambient-temperature metal sputtering

► Graphitic microporous carbon from amorphous carbon by metal sputtering text was fabricated. ► Multilayer graphene is formed via nanoparticle/ion bombardment at room temperature. ► The number of graphene layer formation is controlled by sputtering parameters ► Sputtering plasma manifests activation via dry-etching. ► Energy distribution of sputtered atoms/ions show knock-on effect for graphitization.
