“…Hu et al, reported that for carbon based materials the microwave absorption capacity is highly dependent on their chemical composition and structure. 160 During their study, by varying the oxygen content in GO and/or graphene based materials, the microwave absorption capacity of GO decreased remarkably with increasing of oxygen content due to the decrease of the sp 2 domains. Therefore, pristine graphene is an excellent microwave absorbent compared to GO, which has a relatively poor microwave absorption capacity.…”

In the present investigation, graphene (G) and graphene decorated with Ag (Ag-G), Au (Au-G) metal nanoparticles as well as AuAg alloy (AuAg-G) nanoparticles (NPs) have been successfully synthesized via solution chemical route. The specimens have been characterized by using XRD, Raman, UV-Vis spectroscopy and TEM. TEM study confirms the formation of few-layered graphene sheets decorated with metal and alloy NPs. The relative change in the positions of D and G bands in Raman spectra of Ag-G, Au-G and AuAg-G as compared to graphene reveals a significant electronic interaction between graphene and metal or alloy NPs. A better electronic interaction between AuAg alloy NPs and graphene as compared to that of pure metal NPs has been shown by an enhancement in the intensities of G and D bands in Raman spectrum of AuAg-G as compared to those of Ag-G and Au-G. UV-Vis spectroscopic analysis also indicates, a larger blue shift in the absorption peak of the graphene in AuAg-G than that of metal decorated graphene, suggesting a better interaction between graphene and alloy NPs. These results indicate that alloy NPs can tune the electronic structure of graphene better than metal NPs. Such changes in electronic interaction will lead to modification of the electronic behaviour of graphene, making these materials suitable for many electronic applications.

“…The G band assigned to the first-order scattering of the E2g phonon of sp 2 C atoms in a 2D hexagonal lattice. The D band is associated with the vibration of carbon atoms with dangling bonds in plane terminations of disordered graphite [20]. After the exfoliation process, GO was reduced by the thermal treatment with H 2 gas, the G band was shifted to 1585 cm À1 and the peak intensity ratio I D /I G (Table 1) between D band and G band decreased from 1.1673 to 0.8304, indicating the deoxygenation of GO and the re-establishment of conjugating graphene network.…”

A novel technique for synthesis of thin-layered graphene sheets (GNS) were established by hydrogen-induced reduction of graphene oxide at low temperature of 200 C, using radio frequency chemical vapour deposition. The functional group and microstructures of the prepared GNS were characterised by various techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, Raman spectroscopy and particle-size analyser. Further the as-prepared GNS with an average diameter of 528.8 nm was confirmed by particlesize analyser. This GNS-generation process is rapid with high efficiency of exfoliation process, non-toxic, environmental friendly and ideal for large-scale production for industrial applications.
