Preparation of Modified Graphene Oxide Nanomaterials for Water and Wastewater Treatment

Because of the population explosion, industrialization and environmental disruption which cause big water crisis to all human beings, the development of high-efficient water treatment technologies is highly desirable. Recently, graphene oxide (GO) has drawn wide attention from the scientific community. the two-dimensional GO nanosheets possess high specific surface area and high surface activity, which make GO-based nanomaterials have great potential in various fields. In this paper, recent methods on modification of graphene oxide nanomaterials are introduced and compared. The prospects of GO-based nanomaterials applied in water treatment from three aspects of absorbent, catalysis and membrane separation are further analysed.
