Cobalt oxide/cobalt-based nanoparticles featuring a core–shell structure and nitrogen- doped graphene layers on alumina are obtained by pyrolysis of Co (OAc) 2/phenanthroline. The resulting core–shell material (Co3O4–Co/NGr@ α-Al2O3) was successfully applied in the catalytic hydrogenation of a variety of N-heteroarenes including quinolines, acridines, benzo [h], and 1, 5-naphthyridine as well as unprotected indoles. The peculiar structure of ...
