Abstract: Graphene is easily produced by thermally reducing graphene oxide. However, defect formation in the C network during deoxygenation compromises the charge carrier mobility in the reduced material. Understanding the mechanisms of the thermal reactions is essential for defining alternative routes able to limit the density of defects generated by carbon evolution. Here, we identify a dual path mechanism in the thermal reduction of graphene oxide driven by the oxygen coverage: at low surface density, the O atoms ads… Show more

“…2, in agreement with previous studies where similar groups were reported in thermally treated graphene oxide. 19,20 To build up a strong interface for epoxy/graphene nanocomposites, diaminodiphenylsulfone (DDS) was chosen to react with the epoxide groups of the GnPs. It is worth mentioning that the epoxide groups of GnPs are not sufficiently active to react with the hardener J230 to produce crosslinking; and they also lack in quantity.…”

“…In the present work, we investigate the etching behavior of a closed monolayer, flakes partially covering the surface, and nanoflakes of Gr on Ir(111) when introducing molecular oxygen. Of specific interest is the etching mechanism for the case of the closed monolayer [2,11,25,26], as understanding this might also give insights into the well-known problem of graphite etching [27e29] from a new perspective.…”
