Cobalt-and iron-containing nitrogen-doped carbon nanomaterials are synthesised from 5-methylresorcinol-formaldehyde resin nanospheres by pyrolysis in the presence of nitrogen and metal precursors. Two approaches used for the synthesis yield the catalysts of different morphology, consisting of spherical or irregular porous carbon structures. The electrocatalytic properties of the materials towards the oxygen reduction reaction (ORR) in alkaline solution are evaluated by thin-film rotating disk electrode method. The catalysts containing transition metals exhibit enhanced electrocatalytic activity for ORR as compared to the metal-free nitrogen-doped materials, cobaltcontaining catalysts being slightly more active than iron-based materials. The structure and surface composition of the materials are characterised by scanning electron microscopy, N 2 adsorption studies and X-ray photoelectron spectroscopy.was calculated by using a quenched solid density functional theory (QSDFT) equilibria model for slit type pores.
