Abstract

Nitrogen-doped carbon with a well-dispersed and three-dimensional porous network structure has been fabricated for efficient oxygen reduction reaction (ORR) by using polyacrylamide (PAM) and graphene oxide (GO) as well as a zeolitic imidazolate framework (ZIF) as raw materials. The PAM is favorable for the formation of three-dimensional porous structures, while hightemperature carbonization of the ZIF results in well-dispersed microporous carbon. Among them, Zn-Z/P0.6/G-T calcined at 800°C with a PAM concentration of 60% shows the largest specific surface area (1,458 m 2 /g) and best ORR performance in 0.1 M KOH, giving an onset potential of 0.918 V (vs. RHE), which is even more positive than Pt/C (0.902 V vs. RHE), demonstrating its superior ORR capability. The ORR performance can be further improved by incorporating cobalt into the composite (denoted Co-Z/P0.6/G-T), and this can be prepared by using cobalt nitrate as a metal source. As an ORR catalyst, it exhibits a more positive onset potential (0.935 V vs. RHE) than Zn-Z/P0.6/G-T (0.918 V vs. RHE). The good ORR performance together with its long-term stability and better methanol tolerance make it a promising non-noble catalyst for fuel cell applications.
