A review on tailored graphene material for industrial wastewater

Over the past few years, graphene-based composites have been proved to be one of the most prominent materials of modern times. Graphene based aerogels are the most widely explored 3D-graphene structures for wastewater treatment, owing to its excellent physical and chemical properties. There has been a considerable development in the research of graphene-based materials with the exponential progress of scientific publications in the last five years. This review starts with a background of graphene-based composite, its structural properties and the importance of aerogel material in wastewater treatment. In continuation, a number of recent and emerging experimental procedures for the preparation with particular focus on fabrication techniques and advanced applications in wastewater remediation are elaborated. Techniques, including hydrothermal reduction, chemical reduction, electrochemical reduction, cross-linking, chemical vapor deposition etc. are discussed in detail. Finally, the challenges and research lacunas of graphene based emerging materials and their future perspective in economy are discussed.
