“…These observations are in good correlation with the findings of Kong et al [58], who suggested the presence of absorption peaks at 1020 and 820 cm −1 in the spectrum of V 2 O 5 , resulted from the stretching in V-O bond of vanadyl group (V O) and due to the vibrations in vanadium oxide bridge system (V-O-V), respectively. However, some researchers have also reported that the absorption bands in the region 1100-1050 cm −1 are due to the C-O vibrations resulted from the catalytic cleavage of the iron incorporation, forming the iron oxides on the surface of iron modified activated carbon materials [59][60][61]. In our case, a peak at 1001 cm −1 in all the samples can be attributed to the C-O vibrations.…”

“…These shifts may due to the change in chemical environment of carbon atoms after reduction. 20 In addition, after reduction process, the surface C/O atomic ratio increases from 1.96 (GO) to 6.5 (rGO). These results show that the removal of oxygencontaining groups of GO using caffeine as reduction reagent was relatively successful.…”

A simple and green chemistry approach for the preparation of reduced graphene oxide nanosheets was successfully demonstrated through the reduction of graphene oxide (GO) using caffeine as the reductant. Without using toxic and harmful chemicals, this method is environmentally friendly and suitable for the large-scale production of graphene. The samples of GO, before and after reduction with caffeine have been characterized by X-ray diffraction, Raman, Fourier transform infrared, X-ray photoelectron spectroscopy, thermogravimetric analysis and transmission electron microscopy.

“…The peaks at 1204 and 1042 cm À1 are ascribed to the stretching vibration peaks of -S]O of -SO 3 H in SAC. 23 This peak shied to 10.2 for GO. Further, the peaks related to the oxygen functional groups disappear in SAC-RGO and the appearance of the C]C peak conrms the reduction as well as functionalization of the graphene.…”

“…10,24,25 These peaks are also present in the SAC-RGO conrming the functionalization of RGO by SAC. 23 The appearance of (002) peak at 24.2 for SAC-RGO suggests the reduction or the removal of oxygen functional groups during electro-deposition. The intensity of the -S]O peaks is low in SAC-RGO as compared to SAC and a red shi (from 1042 to 1231 cm À1 ) can be noticed in SAC-RGO due to the p-p interaction.…”

In situ electro-deposition, reduction and functionalization of graphene oxide (GO) with sulfanilic acid azocromotrop (SAC) were carried out through a facile one-step electrochemical method. Nickel foam was used as the anode during the electro-deposition and the aqueous solution of SAC along with GO was used as the electrolyte. The SAC modified reduced GO (RGO) was deposited on the nickel foam (SAC-RGO@Ni) and was directly used as the electrode for capacitive property analysis. The reduction and functionalization of GO were examined by Fourier transform infrared (FT-IR), Raman and X-ray photoelectron spectroscopy (XPS) techniques. The SAC-RGO@Ni provides a very high specific capacitance of $1090 F g À1 due to the synergistic effect of double layer capacitance of RGO and the pseudocapacitance of -SO 3 H functionalities of SAC. An asymmetric supercapacitor (ASC) cell was designed with SAC-RGO@Ni and thermally reduced GO (TRGO) as positive and negative electrodes, respectively. The ASC device exhibits a high effective capacitance of $495 F g À1 at a current density of 10 A g À1 and $93% of its total discharging time lies in-between 1.5 and 0.75 V. The ASC cell remains stable up to 10 000 charge-discharge cycles. Furthermore, the SAC-RGO@Ni-based ASC device can provide a very high energy density of $88.9 W h kg À1 and a large power density of 16 500 W kg À1 ensuring its applicability in high power consumption devices.
