Figure 1 shows the FTIR spectra of GO (graphene oxide) and rGO (reduced graphene oxide/graphene). The GO (graphene oxide) spectrum as shown in Fig.1 shows the peak at 1066 cm-1 is attributed as...

FTIR spectra of GO and RGO. The supercapacitance behavior of hydrothermally reduced graphene oxide (RGO) was investigated for the first time. The capacitive behavior of RGO was...

4、红外光谱分析（FT-IR）： 对所有样品进行FTIR表征，以分析TMPD诱导的表面官能团的变化。GO的FTIR光谱图在3385 cm−1、1730 cm−1、1625 cm−1、1409 cm−1、1170 cm−1、1042 cm−1和876 cm−1都有吸收峰，分别对应于-OH、C=O、C=C、C-OH、C-O、C-H和C-O-C振动。

The FTIR spectra of rGO (Fig. 4c) exhibits band at 3426 cm -1 due to O-H stretching. The band at 1631 cm -1 appears due to C=C stretching. The band at 1198 cm -1 is attributed to the presence...

2023年7月15日 · The various characterisation techniques utilized to analyse the synthesized GO and rGO include X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopic (SEM) images with energy dispersive X-ray spectroscopy (EDX), and Transmission electron microscope (TEM) images.

2024年12月1日 · Graphene oxide (GO) was synthesized by a modified Hummer's method and reduced to rGO using ascorbic acid. The as-synthesized GO and rGO compounds were used to prepare TiO 2: GO/rGO composite thin films by sol-gel spin coating technique. The effect of GO and rGO on the structural, optical, and electrical parameters of TiO 2 thin

2024年1月30日 · In the FTIR spectrum of rGO H samples, the presence of diverse oxygen-containing functional groups is evident. Conversely, the FTIR analysis of rGO E samples reveals a few of such functional groups, aligning with the higher C/O ratio observed in the XPS results.

2019年9月7日 · Graphene oxide (GO) was synthesized by modified Hummer’s method and was reduced by hydrazine (RGO-HZ), ascorbic acid (RGO-AA) and the extract of Amaranthus hybridus (RGO-AH). GO, RGO-HZ, RGO-AA and RGO-AH were characterized using Fourier transform infrared (FTIR) spectroscopy, scanning electron …

2019年8月15日 · The graphene oxide (GO) was converted to reduced graphene oxide (rGO) by chemical reduction using ascorbic acid as the reducing agent. The GO and rGO were characterized by UV-visible spectroscopy, FTIR spectroscopy, and X-ray diffraction patterns.

FT-IR spectrum was recorded and the spectrum of GO obtained confirmed the successful oxidation of the graphite (Fig. 3). Some functional groups such as OAH, CAOH, COOH and CAO were observed.
