Preparation and Characterization of three-Dimensional Graphene Network via two Different Methodologies

Graphene is a single-layer nano-carbon material with outstanding mechanical and physical properties that attracted scientists to explore and study its structure and use it in many critical applications, like supercapacitors, sensors, and nanocomposite materials. Based on its unique properties, numerous techniques for synthesizing 3D graphene structures with a unique lattice structure and significant porosity have been discovered. The CVD technique and the pyrolysis route are two of the most promising methods for producing high-quality 3D graphene using environmentally friendly natural materials. The morphological characteristics of both prepared types were examined using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). On the other hand, the structural properties were investigated using Raman spectra and X-ray diffraction (XRD) measurements. Moreover, this method of synthesis of graphene from asphalt was found to have many advantages, including low cost and ease of production. While the CVD method was characterized by its high quality and control over the number of graphene layers. Thus, the results showed the promising methods used for the synthesis of high-quality 3D graphene.
