Abstract

The scientific community has been more interested in nanomaterials based on graphene for their distinctive chemical and physical characteristics. Recently, agricultural fields have routinely employed graphene oxide (GO). As a result, current study intends to production and characterisation of graphene oxide (GO) investigation, a type of nanomaterial made from graphene. Graphite flakes were used to create the GO material by using a modified Hummers’ process. The X-ray diffraction, Ultraviolet-visible spectrometer, Scanning electron microscopy, Fourier transform infrared, Atomic force microscopy, and Elemental analysis were all used in the GO characterization.
The resulting GO had been evaluated using TEM images, which revealed that the GO sheets exhibited single and double lamellar layer structures with irregular forms and a thickness of 23 nm. The XRD patterns indicated that the GO peak centered at 2θ value 24º corresponds to an interplanar distance of carbon atoms arranged in (002) hexagonal layers; the interlayer spacing is approximately 8.61 Å according to the Scherrer equation. The oxygen-containing functional groups presence in GO films like hydroxyl, carboxyl, epoxy, carbonyl, and C=C bunches was explained by a Fourier-change infrared spectrum analyzer (FT-IR) due to graphite oxidisation in GO without twisting in the graphite layer structure. According to EA findings, the GO sheet's C element content was approximately 47.15 percent, O was 51.8%, H was less than 0.01%, and N was 1.02%. The UV-VIS spectrometer study revealed that the GO sheet exhibited an excellent optical reaction. The thickness and sidelong shape study of graphene oxide sheets by using atomic force microscopy (AFM). The SEM micrographs of GO obtained using modified Hummers handling demonstrate that the GO is made of two-dimensional sheets.
