One-Pot Synthesis of Graphene—Γ-Fe2O3 Composite Through Hydrolysis in A Glycol Medium

A composite comprising graphene and γ-Fe2O3 nanoparticles can be prepared in a glycol medium by a one-pot synthesis starting from graphite oxide, GO, and FeCl3.6H2O. The precursors were dispersed in 1,2-propanediol along with urea as the hydrolysing agent and n-octylamine as the capping agent and the mixture was refluxed. Fe3+ ions undergo hydrolysis to give γ-Fe2O3 nanoparticles and GO gets reduced by glycol simultaneously leading to the formation of graphene—γ-Fe2O3 composite.
