Abstract

Single atom electrocatalysts with typical metal–nitrogen–carbon sites possess good oxygen reduction reaction (ORR) activity, yet challenges remain in fabricating rechargeable zinc–air batteries (ZABs) due to their poor oxygen evolution reaction (OER) performance. Herein, we demonstrated the in situ anchoring of indium clusters on a carbon matrix with iron–nitrogen–carbon sites via the pyrolysis of supermolecule aggregates coordinated with indium and iron ions, aimed to prepare advanced bifunctional electrocatalysts for the ORR and OER. A detailed atomic structure analysis reveals that the modulation of the coordination environment between the indium cluster and iron–nitrogen–carbon sites induces asymmetrical charge distribution to reduce the reaction barrier via the p–d orbital hybridization, thus achieving superior bifunctional electrocatalytic activity. Consequently, the rechargeable ZABs demonstrated a cycling durability of 1650 h. Moreover, the solid-state batteries also exhibited a large power density of 220.0 mW cm−2. This work provides a feasible guidance for rational incorporation of metal clusters with single atom sites to enhance bifunctional electrocatalysis.

长期可充电锌空气电池中铟簇与铁氮原子的耦合研究
具有典型金属-氮-碳位的单原子电催化剂具有良好的氧还原反应(ORR)活性,但由于其析氧反应(OER)性能较差,在制备可充电锌空气电池(ZABs)方面仍存在挑战。本研究通过与铟和铁离子协同的超分子聚集热解,将铟团簇原位锚定在碳基体上,旨在制备先进的ORR和OER双功能电催化剂。通过详细的原子结构分析,铟簇与铁氮碳位点之间的配位环境的调节通过p-d轨道杂化导致电荷分布不对称,从而降低反应势垒,从而获得优异的双功能电催化活性。结果表明,可充电ZABs的循环耐久性为1650小时。此外,固态电池的功率密度也达到220.0 mWcm-2。本研究为合理结合单原子位的金属团簇来增强双功能电催化提供了可行的指导。
