We report a novel chemical vapor deposition (CVD) based strategy to synthesize carbon-coated Fe2O3 nanoparticles dispersed on graphene sheets (Fe2O3@C@G). Graphene sheets with high surface area and aspect ratio are chosen as space restrictor to prevent the sintering and aggregation of nanoparticles during high temperature treatments (800 °C). In the resulting nanocomposite, each individual Fe2O3 nanoparticle...
