Abstract Graphene-Fe{sub 3}O{sub 4} (GN-Fe{sub 3}O{sub 4}) magnetic nanocomposites were prepared, GN-coated magnetic ionic liquid (MIL) as its precursors, which were used as both a magnetic resource and solvent. The method has proved to be valuable for the Fe{sub 3}O{sub 4} nanoparticles (NPs) well dispersed in the solution through strong interactions with GN, which are of interest because of their stability and chemical properties. In the process, strong interactions creates a condition for uniform dispersion in GN and [BMIm]FeCl{sub 4} (MIL) solution, and accelerate the formation of Fe{sub 3}O{sub 4} NPs. A transmission electron microscopy image has shown that the as-formed Fe{sub 3}O{sub 4} NPs with a diameter as small as 5–7 nm were deposited on GN sheets. Furthermore, the final material showed a superior properties than conventional method, which can be ascribed to the fact that [BMIm]FeCl{sub 4} plays a vital role in the process of producing small NPs size.
