“…Similar results were obtained in previous XRD and Raman spectra. From Figure 5D‐F, the C 1s spectra of rGO‐TEA‐3h, rGO‐TEA‐5h, and rGO‐TEA‐10h were deconvoluted into three peaks centered at 284.8, 286.2, and 287.6 eV, corresponding to C–C/C=C, C–OH/C–N and C–O–C, respectively 18,29,30 . Interestingly, there was almost no variation in the content of C–C/C=C from rGO‐TEA‐3h to rGO‐TEA‐10h.…”

Triethanolamine functionalized reduced graphene oxide (rGO‐TEA(s)) nanocomposites have been synthesized by the hydrothermal method. The physical and chemical properties of rGO‐TEA(s) with different degrees of functionalization were characterized by transmission electron microscopy, X‐ray powder diffraction, Raman spectroscopy, and X‐ray photon spectroscopy. The cold rolling lubrication of the rGO‐TEA(s) prepared as nano‐lubricant additives were investigated using a two‐high rolling mill. The microscopic topographies of rolled strips were measured and evaluated by several physical characterizations. The results showed that the increase of functionalization time was favored to the reaction of triethanolamine and C–O–C groups on the GO surface, whereas the defects and disorder in graphene structure were repaired according to the intensity ratio of the D band to G band from 1.154 to 1.130. The cold rolling experiment results demonstrated that rGO‐TEA(s) exhibited excellent lubrication properties, especially the rolled surface lubricated by rGO‐TEA‐10h presented few defects and minimum roughness value. The admirable lubrication performance of rGO‐TEA‐10h was attributed to the formation of absorption film and consecutive carbonaceous protective film.

“…Additionally, some differences are straightforward when observing the low and high relative pressure regimes. At low pressure, the amount of N 2 adsorbed increases rapidly, hence suggesting the existence of micropores in these materials [39]. This is particularly noticeable for IGO, maybe due to a higher density of pores with <2 nm width.…”

“…Whilst the work on this topic is still limited [20,21], there is a prevalence in the literature of GO powders prepared using the classical Hummer's method. Overall, claims of their CO 2 uptake capacity have been markedly disappointing (<1 mmol g −1 ) [16,[22][23][24]. Possible explanations are the limited accessible surface area (commonly <100 m 2 g −1 , cf.…”

ARTICLE INFO ABSTRACTThe influence of the synthesis route on the surface characteristics and CO 2 uptake of graphene oxide was studied. Powders derived from the classical Hummer's method approach and the so-called improved Hummer's method were benchmarked against zeolite 13X and certified carbon nanotubes. With a specific surface area of 283 m 2 g −1 and a CO 2 adsorption capacity of 2.1 mmol g −1 (at 273 K), the improved Hummer's product was superior to the other two nanocarbons tested.
