Design of N-doped graphene-coated cobalt-based nanoparticles supported on ceria

Abstract

A straightforward preparation and detailed characterization of cobalt-based nanoparticles incorporated within a N-doped graphene-type matrix attached to ceria as support (Co3O4/NGr@CeO2) is demonstrated. In general, the active catalytic material is provided by wet impregnation of ceria with a nitrogen ligated–cobalt chelate and subsequent pyrolysis.
