Graphene sheets were prepared by a synthesis method in which aluminum sulfide (Al2S3) was calcined under a mixed gas flow of carbon monoxide (CO) and argon. The reaction of CO with Al2S3 produced alpha-Al2O3 and graphene sheets. The graphene sheets were characterized by X-ray diffraction, high resolution transmission electron microscopy, and Raman spectroscopy. A reaction mechanism is proposed in which CO is reduced to gaseous carbon by the reaction with Al2S3 and the gaseous carbon crystallizes in the graphene sheets. (C) 2009 Elsevier Ltd.
