Preparing graphene based ferroferric oxide nano composite material used as sewage treatment agent, comprises e.g. dissolving soluble ferric salt in deionized water, dispersing graphene oxide, dripping reducing agent, washing, and drying.

ZHANG L, SONG H, MIN C, JIA X, ZHANG S

Surface-modified graphene preparation includes reducing graphene oxide suspension in presence of strong reductant, and preparing graphene into suspension and depositing ferric oxide on its surface by in-situ chemical deposition.

HUANG J, LIU L

Preparing nitrogen-doped graphene/metal oxide nanocomposite, comprises e.g. weighing graphene and metal salt having calcium ion as trivalent/tetravalent metal and then adding to dispersant, and reacting mixed solution with ammonia.

CAI D, LIAN P, LIANG S, WANG H

Preparing ferric oxide/graphene composite, comprises e.g. preparing graphite oxide by Hummers method, Brodie method or Staudenmaier method, dispersing graphite oxide into water, and processing the oxide by ultrasonic wave.
