A composite of porous Fe3O4 hollow microspheres/graphene oxide (Fe3O4/GO) has been
fabricated through a facile self-assembly approach. Driven by the mutual electrostatic
interactions, the amine-functionalized Fe3O4 microspheres prepared by a hydrothermal
method and then modified by 3-aminopropyltrimethoxysilane were decorated with
negatively-charged GO sheets. The Fe3O4 microspheres were hollow with porous surfaces
and the surfaces were successfully modified with the amine, which was confirmed by Fourier …
