“…Further development of the GO-based sensor is also feasible based on its excellent prospective characteristics as a sensor material. The structure and composition of GO can be facilely controlled by several routes, including the hybridization of GO with noble metals, metal oxides, and molecular catalysts; surface functionalization with organic compounds; and the doping of foreign elements into the GO framework. Modification by such methods would drastically change the catalytic and electrochemical properties of the GO membrane, thereby improving the sensitivity, selectivity, and stability of the GO sensor. Because GO itself is a single-layer nanosheet, ultraminiaturization of the electrochemical GO sensor is also possible, as was reported for ultrasmall graphene-based transistor-type gas sensors …”

“…The third signal, centred at 285.39 eV, can be assigned to sp 2 ‐hybridised carbon atoms bonded to nitrogen or oxygen. A fourth signal appears that unlike N‐doped graphene grown directly by the CVD system, [14,17,34] the fourth signal at 289.90 eV is observed in our sample, possibly due to pyridinic nitrogen oxides [35,36] . In research on nitrogen‐doped graphene, the N1s spectrum usually deconvolutes into three individual peaks that are assigned to pyridinic nitrogen (398.1–399.3 eV), pyrrolic nitrogen (399.8–401.2 eV), and quaternary nitrogen (401.1–402.7 eV) with the position varying over a relatively wide range in different studies [31,34,36] .…”

The charge of the nitrogen and its neighbouring atoms and the redistribution of electrons after ionization will influence the precise position of the different types of nitrogen.…”

“…The rGO has been applied recently to reactions such as hydrogenation of nitrobenzene and ozonation of organic phenolics . Alternatively, rGO has been used as nanosupport for metals such as platinum, silver, and gold and nitrogen group , for uses in catalysis, energy storage, and oxidation–reduction reactions.…”

“…Extensive GO characterizations can also be found in our previous papers. 37,38 The high acidity of GO is due mainly to the active carboxyl functionalities on the surface and the unstable epoxy groups. Further, GO may possibly contain some trace amount of sulfonic (SO 3 H − ) group on its surface as a result of its synthesis process.…”
