Characterization and surface modification of carbon nanowalls

Architecting graphene nanowalls on diamond powder surface

“…2 indicates that the average crystallite size in the GNWs is 20-30 nm. This is consistent with reported domain sizes for standing multiple-layer GNWs [24,25]. The G band peak is accompanied by a shoulder peak at 1618 cm À1 (D 0 band), which is associated with finite-size graphite crystals and graphene edges.…”

Surface Chemical Modification of Carbon Nanowalls for Wide-Range Control of Surface Wettability

“…CC (sp 3 ) bond peaks (C1) were also found at 285.1 eV. These relatively‐sharp C0 peaks and broad C1 ones were characteristic peaks assigned to the six‐membrane ring structures of graphene and their disordered structures, respectively . It is found that the intensity ratio and shapes of C0 and C1 peaks hardly changed even after the plasma surface treatments.…”

Carbon nanowalls thin films as nanostructured electrode materials in vanadium redox flow batteries

“…A general survey scan showed that C and O were the major elements present in the CNWs films (Table 1). Since oxygen is not used in the synthesis process, the O signals recorded originate from small amounts of oxygen or water adsorbed from air (not only physically but also chemically bonded) on the surface [30]. In addition, it can be assumed that most of the oxygenated functional groups, which could act as active sites towards the vanadium redox reactions, are situated on the edges of the CNWs [31].…”
