Graphene oxide and reduced graphene oxide are valuable graphene derivatives. Graphene oxide and reduced graphene oxide show different chemical and structural properties due to the differences in their chemical compositions. The most prominent differences are observed in the electrical conductivity, hydrophilic behavior, mechanical strength, and dispersibility of these materials. Different properties of graphene oxide and reduced graphene oxide are utilized in energy storage applications, sensors, supercapacitors, solar cells, and biomedical applications. Graphene and Its Derivatives Allotropes of carbon such as diamond and graphite have been amongst the most important materials from the day of their discoveries. Graphite is composed of hexagonal carbon crystal sheets stacked on top of each other. It is a naturally occurring allotrope of carbon and the most stable form under standard conditions. Graphite has been used for several different purposes since the 1500s; however, most import...

Reduced graphene oxide is produced from graphene oxide by ultrasound, chemical or thermal reduction. During the reduction step, most of the oxygen functional groups are removed from graphene oxide, so that the resulting reduced graphene oxide has very similar properties to pure graphene. However,  reduced Graphene Oxide  is not defect-free impure than pure graphene. The main difference between graphene oxide and reduced graphene oxide is the decrease in the ratio of the number of oxygen atoms to that of carbon atoms present in the structure.  This article discusses reduced Graphene Oxide, its properties, production methods, and applications. 9 Core Properties of rGO The core properties of reduced Graphene Oxide are given below: The  electrical conductivity of Reduced Graphene Oxide  is 666,7 S/m. rGO is mainly produced by the chemical reduction method. Reduced Graphene Oxide is black in color. rGO exists in the powder form. rGO is odorless. BET s...
