摘要：

This study investigated the structures and compositions of two types of graphene (GP) produced by the reduction of graphene oxide (GO): GP(TR). produced by thermal reduction at 1073 K in N-2; and GP(CR). chemically reduced with hyrdazine. GP(TR) and GP(CR) have a small number of surface oxide groups with the compositions C100O3+/-1 and C100O6.5+/-2 and consist of six layers and three layers, respectively. The interlayer spaces are slightly larger than those in typical graphene produced by "top-down" exfoliation from graphite. These structures and compositions are intrinsic properties of graphene produced by the "bottom-up" layer-by-layer stacking process. (C) 2009 Elsevier B.V. All rights reserved.
