Preparation of graphene relying on porphyrin exfoliation of graphite.
A new method for the preparation of graphene has been developed via porphyrin exfoliation of graphite in NMP. The exfoliation, which follows the intercalation of organic ammonium ions, is based on the pi-pi interaction between graphene and porphyrins. The graphene sheets prepared by this method show undisturbed sp(2) carbon networks.
