Abstract
In this study, graphene oxide−magnetic nanoparticle composites were prepared by attaching magnetic nanoparticles to graphene oxide through a high temperature reaction of ferric triacetylacetonate with graphene oxide in 1-methyl-2-pyrrolidone. X-ray diffraction, transmission electron morphology, and thermogravimetric analysis were used to demonstrate the successful attachment of iron oxide nanoparticles to graphene sheets. It was found that the attached nanoparticles were mainly magnetite. Investigations using Fourier transform infrared spectroscopy proved that the tight attachment was due to the robust linkage: metal−carbonyl coordination.
