The development of cost-effective, sustainable and environmental-friendly energy conversion and storage devices is a key path towards carbon neutrality. Rechargeable zinc-air batteries (ZABs) are amongst the most promising battery technologies as they combine high energy density (theoretical limit: 1086 Wh kg -1 ), economic viability and feasible scale-up. However, the sluggish kinetics of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) result in high overpotentials and unsatisfactory efficiency, thereby causing major roadblocks in the development of ZABs. While noble metal-based catalysts might address some of these issues, their scarcity and high cost prohibit large-scale commercialization. Thus, the development of highly efficient and robust bifunctional catalysts (DACs). Compared with SACs, the DACs comprise adjacent hetero-metal pairs (Fe-Co, Co-Mn, Co-Ni), exhibiting asymmetric charge distribution at the active sites, which is a promising means to improve oxygen intermediate adsorption and desorption, and it can lower the energy barriers for O2 activation. Moreover, synergistic effects at the dual-metal site can enhance overall catalytic performance for both ORR and OER. Despite major efforts in the field, the development of bifunctional DABs for use in ZAB is still in its infancy, and the design of robust catalysts as well as precise control of the coordination environment are still major bottlenecks. To date, 2D-and 3D-structured nitrogen doped carbon matrices derived from metal-organic frameworks (MOFs) are often used for anchoring SACs. While these materials offer facile synthetic access, they often result in active sites hidden inside the composite, and in consequence, mass transfer to/from the catalyst often becomes the limiting parameter. Thus, structural and morphological engineering of nitrogen doped carbon substrates is of great significance to fully expose active sites and ensure efficient electron and mass transfer. To overcome these challenges, SAC composites have been combined with multi-walled carbon nanotubes (MWCNTs). MWCNTs feature one-dimensional (1D) structures with outstanding chemical and thermal stability, high specific surface area and excellent electrical conductivity, making them ideal substrates for bifunctional ORR/OER electrocatalysts. In one outstanding example, Masa and co-workers reported an oxygenfunctionalized MWCNTs as substrate for trimetallic (Mn-Fe-Ni) oxide nanoparticles, exhibiting remarkable ORR and OER performances. Also, Streb, Liu and coworkers used a facile one-pot assembly synthetic route to deposit nanostructured manganese vanadium oxides on nitrogen-sulfur functionalized MWCNTs, which showed excellent ORR and OER performance. However, establishing a chemical and electronic linkage between the reactive sites and charge transfer materials (MWCNTs) remains challenging, and often results in poor interfacial conductivity and poor long-term stability. Recently, Sun and colleagues reported an atomically dispersed Fe-N-C catalyst fabricated from a Fe modified zeolitic imidazolate framework (ZIF-8), which demonstrated impressive performance for both ORR and ZABs. Liu and collaborators also employed ZIF-8 as template and successfully prepared a bifunctional FeCo-NC catalyst for ORR and OER, enabling stable long-term ZAB operation. Here, we build on these pioneering studies and aim at designing bifunctional ORR/OER composites where ZIF-derived DACs on N-doped carbon are electrically "wired" to MWCNTs to harness synergisms for high-performance, robust electrocatalyst materials design. We proposed a strategy for anchoring FeNi dual-metal sites on nitrogen-doped carbon enwrapped by conductive MWCNTs via a simple two-step process (denoted as FeNi-NC@MWCNT). The resulting catalyst demonstrated excellent bifunctional OER and ORR reactivity, outperforming the benchmark Pt/C + IrO2 and various related reference catalysts. Complementary experimental and theoretical analyses provided unique information on the reaction mode and synergism of these dual sites, offering distinct reactions pathways which are energetically not accessible by single metal site reference catalysts. Practical applicability and stability of the catalyst was demonstrated by integration in an aqueous rechargeable ZAB which showed excellent performance in long-term cycling tests.
