Structure and Electrochemical Properties of Graphene, Derivatives, and Its Nanocomposites

Graphene is a form of carbon with a two-dimensional structure organized in a plane and looks like a honeycomb network. Graphene may assist the amount of electricity passing more than six times higher than copper. Graphene possesses good electrical, mechanical, and thermal characteristics along with other unlikeness-like magnitude relations with great specific surface area compared to other nanoparticles. Additionally, to provide an acceptable possibility of mechanical support, still, there are probabilities of being used to regulate functional features including impermeability to gases, expansion, and stability. Graphene sheets have a higher surface area-to-volume ratio with exceptional electronic transport features. These characteristics guarantee graphene to be used in various areas like solar cells, sensors, batteries, membranes, medicines, supercapacitors, and hydrogen storage. Developing composites of graphene contributes a lot to their application. The electrochemical properties of graphene rely on their surface charge and how electrons move conveniently in graphene electrodes; this was examined by using redox reaction and potassium ferricyanide. Furthermore, the unlikeness features of graphene and its derivatives (such as graphene oxide, graphene quantum dots, reduced graphene oxide, graphane, graphone, graphyne, graphdiyne, and fluorographene) bring more awareness to probable significance in several dimensions like Nanobiotechnology, biomedicine, and biosensors.
