Graphene sheets were prepared by a synthesis method in which aluminum sulfide (Al(2)S(3)) was calcined under a mixed gas flow of carbon monoxide (CO) and argon. The reaction of CO with Al(2)S(3) produced alpha-Al(2)O(3) 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 Al(2)S(3) and the gaseous carbon crystallizes in the graphene sheets.
