Graphene Alloy with Nano Carbon: Novel Nano Material for Biosensor?

摘要

We have discovered an unusual type of nano carbon which exhibits super high electrical conductivity over well known SWNT (single walled carbon nano tube) and graphene nano platelets. The new nano carbon material is suspected to be a graphene hybrid composite with some portions of tubular nano carbon including carbon nano tube, carbon nano rod and carbon nano wire. As the tubular shape nano carbon is always observed at low catalyst portion (MS/CS ratio, MS= Metal Source , CS= Carbon Source) while graphene related structure is always observed at much higher concentration of the catalyst, we assume that the extra amount of catalyst could work as a divider to separate single sheet of carbon into graphene products . The nano carbon materials of the present study are synthesized by the unoxidizing pyrrollysis of salt-milled solid carbon sources using specific catalyst...
