▎ 摘　　要

A straightforward preparation and detailed characterization of cobalt-based nanoparticles embedded in nitrogen-doped graphene-type layers (NGr's) on ceria as support is described. Such advanced materials are provided by wet impregnation of ceria with nitrogen ligated-cobalt complexes and subsequent pyrolysis under inert conditions. Preliminary tests of these materials demonstrate their activity for industrially relevant catalytic hydrogenations of ketones.
