Abstract	Researchers created Co/CoO nanoparticles coated with graphene layers (Co/CoO@Carbon) via direct heating treatment of cobalt oxide precursors deposited over nanographite materials. Cobalt oxides are partially reduced to active zero-valent metal species and the simultaneous formation of carbon layers over the nanoparticles protects them from oxidation and deactivation. This nanocatalyst performs excellently in chemoselective hydrogenation of some challenging nitroarenes with reducible functionalities to the corresponding anilines.
