Site-specific fabrication of graphitic microporous carbon terminated with ordered multilayer graphene walls

Abstract

The site-specific fabrication of metal-incorporated graphitic microporous carbon terminated by highly ordered multilayer graphene walls via an ambient-temperature vacuum-based process is presented for the first time. Sputtering of Cr nano-particles on the ultrathin amorphous carbon film manifests a dual effect of activation via dry-etching by the sputtering plasma and of ‘knock-on' inelastic collision between nanoparticles and C atoms for structural ordering. This novel and simple method is very useful for fabricating high surface area carbon nanostructures for hydrogen storage and clean energy applications.
