Mn/Co co-doped porous carbon material derived from self-assembly of CoPc and ZIF-11 for oxygen reduction reaction

Developing low-cost, high-performance oxygen reduction reaction (ORR) electrocatalyst plays a key role in promoting the low-carbon green production. Herein, a Mn/Co co-doped carbon-based non-noble metal electrocatalyst (NNME) with enhanced ORR performance was prepared by simply pyrolyzing the self-assembly induced complex precursor of CoPc@Mn-ZIF-11. The obtained NNME demonstrates the half-wave potential of 0.864 V (vs. RHE) in 0.1 M KOH aq., which is comparable to that of the commercial 20 Self-assembled CoPc with Mn-ZIF-11 derived electrocatalyst with enhanced ORR activity than the mechanically mixed method
