Graphene oxide (GO) and reduced graphene oxide (RGO) are known to have superior properties for various applications. This work compares the properties of GO and RGO with graphite....

The XRD result for GO presented in Fig. 1 (a) shows the appearance of peak at 2θ = 10.5°, indicated the formation of graphite oxide structure and the disappearance of peak at 2θ = 26.6° in The...

Exposure to GO and rGO induced significant production of superoxide radical anion compared to control. GO and rGO showed dose-dependent antibacterial activity against P. aeruginosa cells through the generation of reactive oxygen species, leading to cell death, which was further confirmed through resulting nuclear fragmentation.

2019年12月12日 · The XRD and FTIR investigation shows the strong π–π stacking interactions between the layered GO host–RGO guest sheets. An improvement in PEC water reduction activity was exhibited by RGO/GO nano-hybrid photoelectrode, with a maximum photocurrent of − 61.35 μA/cm 2 for RGO 1 wt% in GO versus − 42.80 μA/cm 2 for pristine GO ...

The XRD pattern of rGO was compared to the GO pattern (inset graph in Fig. 1 (a)) which shows the (001) plane around 10 • whilst rGO shows the (002) plane around 26 • , confirming that the ...

2014年8月1日 · The commercial and synthesised few-layer graphene oxide, prepared using oxidation reactions, and few-layer reduced graphene oxide samples were structurally and chemically investigated by the X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron spectroscopy methods, i.e. X-ray photoelectron spectroscopy (XPS) and reflectio...

2017年12月18日 · In the present investigation, GO was prepared by exfoliation of graphite using modified Hummer's method and then reduced using hydrazine hydrate (reducing agent) to produce rGO. XRD, FESEM, Raman, FTIR spectrophotometer and TGA were used for characterization of GO and rGO. XRD images reveal crystalline structure for both GO and rGO.

Characterization of GO and rGO Fig. 4 shows the XRD spectra of the GO and rGO samples synthesized from the natural graphites with different degrees of graphitization. The characteristic diffraction peaks of the GO samples corresponding to the (002) plane were observed at 2θ = 10° with an average d-spacing of around 0.79 nm, as shown in Fig. 4a.

2018年2月23日 · We report a facile and cost-effective approach to develop self-standing reduced Graphene Oxide (rGO) film based optical sensor and its low-temperature performance analysis where midgap defect...

2019年12月1日 · XRD of the GO, PMMA, and GO-PMMA suggested that polymer particles on surface of the GO layers inhibited the re-stacking of GO nanolayers, and SEM revealed the average lateral size of the initial GO sheets [120].
