Single iron atoms coordinated g‑C3N4 on hierarchical porous N-doped carbon polyhedrons as a high-performance electrocatalyst for oxygen reduction reaction

Abstract

Isolated single Fe atoms coordinated graphitic carbon nitride (g-C3N4) dispersed on hierarchical porous N-doped carbon polyhedrons (Fe-g-C3N4/HPNCP) catalysts were successfully prepared. The optimized Fe-g-C3N4/HPNCP-0.8 shows excellent electrocatalytic activity for oxygen reduction reaction under alkaline condition with a half-wave potential of 0.902 V, significantly outperformed commercial Pt/C, as well as high durability. The high performance stems from the synergistic effect of the atomically dispersed Fe-N2 sites and the advantages of the hierarchical porous structure for promoting the mass transport and improving the accessibility of active sites.
