Evaluation of waste human hair as graphene oxide and examination of some characteristic properties [Atık ?nsan saçının grafenoksit olarak değerlendirilmesi ve bazı karakteristik özelliklerinin ?ncelenmesi]

Abstract

In this study, graphene oxide was synthesized from activated carbon obtained from waste hair for the first time using Modified Hummers method. the Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), Raman Spectroscopy and X-Ray Diffraction (XRD) analysis results of synthesized graphene oxide were examined. In SEM images, graphene oxide structures were observed as very thin layers. In addition, the characteristic peaks of graphene oxide were observed in FT-IR spectroscopy and Raman spectroscopy. In the XRD spectra, reflections of the graphene oxide were seen in plane (001) at 2?=13.66. It was determined that this structure was hexagonal crystal structure. The distance d (6.39Å) between the planes and the weave parameters were determined to be 12.80 Å. The transformation process for actived carbon production from human hair waste was patented by Turkish Patent and Trademark Office (Turkish Patent Institute Application Number: (2017/10764). © 2020, TUBITAK.
