Graphene nanosheets by low-temperature thermal reduction of graphene oxide using RF-CVD

Abstract

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 particle-size 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.
