An efficient carbon-based hybrid electrode in the capacitive deionization process

A cutting-edge technology called capacitive deionization (CDI) has been successfully applied in several water treatment and purification applications. In several instances, compared to other modern technologies, CDI technology has demonstrated enhanced efficiency. Recent advancements in this area have improved CDI performance by increasing the system's total adsorption capacity [۱]. Graphene oxide (GO) is one typical two-dimension structured and oxygenated planar molecular material. graphene oxide is greatly wanted for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. There are many chemical methods for the chemical synthesis of graphene oxide [۲]. Here, we describe a green method of producing graphene oxide electrochemically and how it may be used in a CDI system. In our electrochemical oxidation reaction, the graphite lattice is oxidized within a few seconds, and the produced graphene oxide is identical to that obtained by the chemical techniques. We thoroughly constructed a CDI setup and examined the functionality of three different graphene oxide-based electrode types. Synthesized graphene oxide was characterized by FTIR and Raman spectroscopy methods and compared with chemical methods in terms of quality and water consumption. The amount of salt absorption of electrodes made in an ideal CDI setup was compared, and electrochemical tests were taken from them.
