Outline of Final Research Achievements

Graphene with one layer structure of graphite is expected to be applied for electrodes and catalyst supports. This work synthesized graphene without decomposing the structures of precursors by proceeding only dehydrogenation reactions. The graphene was analyzed by combining transmission electron microscope (TEM) and various spectroscopy techniques. Unlike conventional graphene, this work could synthesize graphene using precursors of azulene at low heat treatment temperatures. The structures of graphene were revealed by TEM observation, Raman spectra, and C1s XPS spectra. Nitrogen-doped graphene with close to one type of functional groups could be synthesized using phenazine.
