Water decontamination by 3D graphene based materials: A review

3D graphene and its derivatives have attracted widespread attention as novel material for the adsorption and photocatalysis of wastewater contaminants. Because of unique physicochemical properties and easy regeneration abilities, it can be an excellent and most efficient material for the treatment of water pollutants. 3D graphene aerogels have been proven to be very powerful removing agents of wastewater contaminants like heavy metals, chemicals, dyes, oils and solvents. Literature reports that the mesoporous and macroporous structure of 3D graphene based materials (3DGBMs) provide better and efficient results compared to conventional graphene in adsorption and photodegradation of water contaminants. There are several other applications of 3DGBMs, however this review focuses on the removal of wastewater contaminants. Discussions, commentary and analyses have been added for the synthesis and application of 3DGBMs in wastewater only. This review will help to find out all the latest work on 3DGBMs towards the decontamination of wastewater pollutants.
