Tailored graphene materials by chemical reduction of graphene oxides of different atomic structure. Botas, C., Alvarez, P., Blanco, C., Dolores Gutierrez, M., Ares, P., Zamani, R., Arbiol, J., Morante, J. R., & Menendez, R. RSC ADVANCES, 2(25):9643-9650, 2012. doi abstract bibtex Graphene materials with different characteristics in terms of sheet size and defects (structural and/or functional groups) were obtained by the reduction with hydrazine of two graphene oxides with similar oxygen content, but with functional groups of different type and location. The oxides were prepared from two synthetic graphites with distinct crystalline structure. Our research has obtained experimental evidence of a greater reactivity of the oxygen functional groups located in the interior of the aromatic domains on the basal planes (mainly epoxy) and a lower reactivity of oxygen functional groups located at the edges (mainly carboxyl and OH). Furthermore, these edge-located groups were found to be responsible for hydrogen bonding lateral interactions between sheets (these occur through the residual OH groups), which cause a substantial increase in the size of the reduced graphene oxide with respect to that of the parent graphene oxide. These results offer a way to tailor the characteristics of graphene materials for diverse applications.
