A facile chemical method to produce superparamagnetic graphene oxide–Fe3O4 hybrid composite and its application in the removal of dyes from aqueous solution†
Abstract
A superparamagnetic graphene oxide–Fe3O4 hybrid composite (GO–Fe3O4) was prepared via a simple and effective chemical method. Amino-functionalized Fe3O4 (NH2-Fe3O4) particles are firmly deposited on the graphene oxide sheets. The graphene
