Abstract:
GO ( graphene oxide) is a monolayer of graphite oxide. The characterization of graphene oxide as raw material in making their experimental results including: oxidation mechanism, structure, morphology, reduced.
Graphene oxide was characterized by spectroscopic techniques, such as solid-state nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), X-ray absorption near-edge spectroscopy (XANES), Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy, can provide essential insights into the types of oxygenated functional groups in GO and their distributions. Besides, microscopic techniques including transmission electron microscopy (TEM), scanning tunneling microscopy (STM), atomic force microscopy (AFM) and scanning transmission electron microscopy (STEM) have also been used to determine the atomic structures of GO.
Their structural, thermal, optical, and electrical properties were also discussed along with their potential applications. Among different reduction methods, the chemical reduction can occur at low or moderate temperatures with the help of reducing reagents, which is one of the most commonly used approaches to transform GO back into graphene.
The aim of this paper is to provide a comprehensive scientific progress of graphene oxide to date and evaluate its future perspective.
