| 英文摘要 | A novel hybrid, with g-C3N4 embedded CoO particles covalently supported on a two-dimensional graphene sheet, is synthesized by a facile and scalable method towards the oxygen reduction reaction (ORR) for fuel cells. The composite hybrid with a suitable loading of g-C3N4@cobalt oxide on graphene exhibits excellent electrocatalytic activity and a dominant four-electron oxygen reduction pathway in basic solution. The kinetic-limiting current density (J(k)) is 16.78 mA cm-2 at -0.25 V, approaching that of 20% Pt-C (17.22 mA cm-2) at the same potential. The performance gap between the hybrid and 20% Pt-C in terms of the half-wave potential difference (⊿ E1/2) is 25 mV in alkaline solution. Furthermore, the hybrid is robust and methanol tolerant, making it a good candidate as a cathodic electrocatalyst in fuel cells. |
