The structural analysis of various hydro-graphene species
2004
Abstract The marginal members of the carbon allotropes containing a significant amount of hydrogen atoms are of interest because they show a variety of interesting properties lacking pure carbon materials. They consist of many fractions of highly condensed aromatic rings and are characterized by the atomic ratio of hydrogen-to-carbon ([H]/[C]). A finite part of a graphite sheet is often called “graphene”. The graphenes terminated by hydrogen atoms like highly condensed aromatic rings may be called “hydro-graphene”. In this paper, we carried out the structural analysis of six kinds of “hydro-graphene” materials prepared by the pyrolysis of three different raw materials at 550 and 650 °C. The TEM results are consistent with the XRD analysis and clearly indicate the size of the crystallite structure and unique interlayer distance in each hydro-graphene material. These methods may be effective for the design of various kinds of hydro-graphenes and preferable applications of these materials.
