Oxidizing metal ions with graphene oxide: the in situ formation of magnetic nanoparticles on self-reduced graphene sheets for multifunctional applications.

چکیده
Fe(2+) cations in FeCl(2) or FeSO(4) were oxidized by graphene oxide, leading to an in situ deposition of Fe(3)O(4) nanoparticles onto the self-reduced graphene oxide (rGO) sheets. The resultant Fe(3)O(4)/rGO sheets were demonstrated to possess interesting magnetic and electrochemical properties attractive for a large variety of potential applications.
