“…In addition, the generated hierarchical structure can facilitate the electrolyte to enter the internal space of the catalyst and ensure the transmission of electrons and electrolyte during the electrocatalysis process. [40,41] Herein, by using a novel tri-metal ZIFs with cruciform shape as precursor, we first report the preparation of Co 5.47 N and Co 7 Fe 3 (CoFeN) embedded in 1D N-doped carbon nanotubes modified 3D cruciform carbon matrix (NCNTs//CCM). As trifunctional electrocatalyst, the obtained CoFeN-NCNTs//CCM shows excellent activities toward ORR, OER, and HER and high stability.…”

Developing low-cost, efficient, and stable trifunctional electrocatalyst for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) is still a significant challenge. Herein, this study reports a zeolitic imidazolate framework (ZIF) derived trifunctional electrocatalyst, composed of Co 5.47 N and Co 7 Fe 3 (CoFeN) that embedded into 1D N-doped carbon nanotubes modified 3D cruciform carbon matrix (NCNTs//CCM). Benefiting from the robust interfacial conjugation of Co 5.47 N/Co 7 Fe 3 and the 1D/3D hierarchical structure with a large surface area, the as-prepared CoFeN-NCNTs//CCM display trifunctional electrocatalytic activity for ORR (half-wave potential of 0.84 V), OER (320 mV at 10 mA cm -2 ), and HER (−151 mV at 10 mA cm -2 ). The assembled Zn-air battery exhibits high power density (145 mW cm -2 ) , enhanced charge-discharge performance (voltage gap of 0.76 V at 10 mA cm -2 ), and long-term cycling stability (over 445 h). The resultant overall water-splitting cell achieves a current density of 10 mA cm -2 at 1.63 V, which can compete with the best reported trifunctional catalysts. What is more, the self-assembled Zn-air batteries are utilized to power the overall water splitting successfully, verifying great potential of the CoFeN-NCNTs//CCM as functional material for sustainable energy storage and conversion system.

“…Results showed that it exhibited good bifunctional ORR and OER activities under alkaline condition compared to commercial Pt/C and IrO 2 , in which exhibited maximum power density of 220 mW/cm 2 at 0.72 V and good cycle durability in Zinc-air battery. Recently, Chen et al [29] studied the Fe-N-C electrocatalyst prepared by converting modified Fe-phenanthroline into Fe-NCDNA using methanol as solution. They concluded that Zn-air battery delivered maximum power density of 184 mW/cm 2 .…”

It is critical to study efficient, stable oxygen reduction reaction (ORR) electrocatalysts due to insufficient stability and expensive price of Pt/C catalysts for Zn-air batteries. Fe-N-C electrocatalysts was synthesized by a facile solvent-green method and the efficiency of Fe-N-C optimized was studied as potential ORR electrocatalysts under alkaline condition. Results indicated that it had excellent ORR activity with E 1/2 of 0.93 V, which was competitive to that of Pt/C-JM under the same conditions. Moreover, the assembled Zn-air battery exhibited discharge potential and charge potential of 1.2 V, 2.32 V at 5 mA cm −2 with high stability, respectively. Overall, all results illustrated that Fe-N-C is an excellent ORR electrocatalyst in the field of metal air battery. Additionally, this work opens a good way to synthesize highly efficient electrocatalysts from metal organic framework and to investigate ORR mechanism of efficient chemical energy to electricity conversion.
