Synthesis and characterization of advanced carbon materials, including graphene, has accelerated over the past several years at the Oak Ridge National Laboratory. Projects include, among others, the development of nanostructured carbon materials for batteries, fuel cells and as supports for revolutionary catalysts. The past year has also brought to ORNL new projects related to the growth, characterization and application of graphene. This poster will highlight x-ray photoelectron spectroscopy and scanning Auger microanalysis of a variety of important carbon materials from several of these research projects, including nano-sized carbon powders for battery applications, graphitic carbon powders used in fuel cells, graphene flakes synthesized for supporting catalyst materials and CVD grown graphene. In particular, an approach for curve fitting highly graphitic materials will demonstrate internally consistent results, giving insight into the sp2 vs. sp3 type carbon atoms present in the material.
