Abstract
The oxygen reduction reaction (ORR) is the cornerstone reaction of the cathode in metal-air batteries; however, slow kinetics requires high-performance catalysts to promote the reaction. Polyphthalocyanine (PPc) has a typical chemical cross-linking structure and uniformly dispersed metal active sites, but its poor activity and conductivity limit its applications as an ORR catalyst. Herein, a manageable and convenient strategy is proposed to synthesize ternary ORR catalysts through the low-temperature pyrolysis of FePPc. The optimal catalyst, Fe3O4/Fe3N/Fe-N-C@PC-2.5, exhibits excellent ORR activity in alkaline solution with a half-wave potential of 0.90 V, which is significantly higher than that of commercial 20% Pt/C (0.84 V). Electrochemical tests and extended X-ray absorption fine structure spectroscopy reveal that the superior ORR activity of Fe3O4/Fe3N/Fe-N-C@PC-2.5 could be ascribed to the balance of its ternary components (i.e., Fe3O4, Fe3N, and Fe-N4 species). A Zn-air battery incorporating Fe3O4/Fe3N/Fe-N-C@PC-2.5 as an air cathodic catalyst delivers a high open-circuit voltage and peak power density. During galvanostatic discharge, the battery demonstrates a specific capacity of 815.7 mA h g−1. The facile strategy of using PPc to develop high performance composite electrocatalysts may be expanded to develop new types of catalysts in the energy field.
摘要
聚酞菁具有典型的化学交联结构和均匀分散的金属活性位点, 但是较差的活性和导电性限制了其作为氧还原催化剂的应用.本文通过热解聚酞菁铁与多孔碳的混合物制备了三元氧还原催化剂, 产物Fe3O4/Fe3N/Fe-N-C@PC-2.5在碱性溶液中的半波电势为0.90 V, 远高于市售20% Pt/C的半波电势. 电化学测试和X射线吸收精细结构相结合, 将Fe3O4/Fe3N/Fe-N-C@PC-2.5的优异氧还原活性归因于Fe3O4, Fe3N和Fe-N4三种组分的共存. 以Fe3O4/Fe3N/Fe-N-C@PC-2.5作为空气阴极催化剂的锌空气电池具有较高的开路电压和峰值功率密度. 在恒电流放电过程中, 该电池的比容量可达到815.7 mA h g−1.
