N2 - This study synthesizes the nickel-cobalt supported by the metal-organic framework CPO-27 (coordination polymer of Oslo, Ni-Co-CPO-27) and g-C3N4, showing outstanding catalytic activity and stability for oxygen reduction reaction in alkaline media, notated by NiCo2-CPO-27/PCN-HT (PCN-HT: heat-treated polymeric carbon nitrite). The half-wave potential of NiCo2-CPO-27/PCN-HT is 0.82 V, and the electron transfer number is around 3.99, which is close to the activity of Pt/C. The stability test of NiCo2-CPO-27/PCN-HT demonstrates only 0.01 V decade of the half-wave potential after 30,000 cycles. The synergistic effects of Ni-Co metals, pyridinic-N species, and graphitic-N species contribute to the outstanding performance of NiCo2-CPO-27/PCN-HT. The anion exchange membrane fuel cell (AEMFC) using NiCo2-CPO-27/PCN-HT in the cathode shows excellent performance with a maximum power density of 224.4 mW cm-2, 20% higher than AEMFC using the Pt/C under the same condition.
