ABSTRACT
The emerging development of graphene-based electrodes is critically reviewed. These promising materials have shown to enhance the electrochemical advanced oxidation processes (EAOPs) efficiency during wastewater treatment. Thorough investigations, the main factors responsible of the success of such cathode in undivided electrolytic cell have been identified as follows: (1) carbonaceous raw material, (2) nanostructured-coated materials, (3) high-porosity materials, and (4) nitrogen-doped materials. These parameters participate to the enhancement of electroactive surface area and conductivity of electrode, two main material’s properties that affect its efficiency. By combining all these characteristics, graphene-based electrode322 opens up new exciting EAOPs setups and should bring them closer to real applications.
