| 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. (© 2012 WILEY‐VCH Verlag GmbH & Co.
