Preparation of multifunctional water separator materials based on graphene oxide nanoribbons used e.g. for heavy metal adsorption by mixing phosphoric acid and sulfuric acid, adding carbon nanotubes and potassium permanganate and filtering.

FAN Z, LIU Y, WANG Y, ZHANG E, SUN X

Preparing graphene-metal chalcogenide porous material used in e.g. water treatment, involves adding metal precursor and chalcogenide precursor to dispersion comprising graphene oxide, heating obtained mixture and freeze-drying gel.

ZHANG H, BI H, CHEN B, MA Q

Sponge like nanomaterial obtained from graphene oxide by sonicating graphene oxide in deionized water solution and freezing, used e.g. as supercapacitor, in construction of lithium battery and separating oil from water.

CHIU G, YU A

Manufacture of isotopic filtration module for e.g. filtering nuclear power plant waste water stream involves dispersing graphene oxide flakes in aqueous medium to oxide solution and applying graphene oxide solution to substrate.
