Graphene oxide and its derivatives: preparation, characterization and applications Line of research Starting from graphene oxide (GO), its variably "reduced" derivatives are synthesized with chemical, thermal and electrochemical methods. Nanostructured hybrid materials are also prepared through GO functionalization reactions with molecules with specific functions (redox, chelating, sensitizing). These materials are investigated by photoemission spectroscopy (XPS), UV-vis, Raman, FTIR, electrochemistry, microscopy and theoretical calculations. Possible applications are in the biomedical, energy and environmental fields.
