Fabrication and characterization of the FeO@SiO-rGO nanocomposite: a catalyst for multi-component reactions.

A novel nanocomposite is synthesized by covalently modifying reduced graphene oxide (rGO) with FeO@SiO nanoparticles. FeO was synthesized using a co-precipitation method, and SiO was then coated onto the FeO a sol-gel method. Graphene oxide was synthesized using the Hummers' method.
