abstract = {This work shows the preparation of carbon nanospheres with a high superficial nitrogen
content (7 wt.%), obtained by a simple hydrothermal method, from pyrocatechol and formaldehyde,
around which tungsten nanophases have been formed. One of these nanophases is tungsten carbide,
whose electro-catalytic behavior in the ORR has been evaluated together with the presence of nitrogen
surface groups. Both current and potential kinetic density values improve considerably with the
presence of tungsten, despite the significant nitrogen loss detected during the carbonization treatment.
However, the synergetic effect that the WC has with other electro-catalytic metals in this reaction
cannot be easily evaluated with the nitrogen in these materials, since both contents vary in opposite
ways. Nevertheless, all the prepared materials carried out oxygen electro-reduction by a mixed
pathway of two and four electrons, showing remarkable electro-catalytic behavior.},
