“…Thus, the design and construction of multi-shell 2D MOFs provide new opportunities for energy conversion and storage applications. Besides, trimetallic catalysts are also studied for oxygen catalysis for the potential synergetic effect [ 134 ]. Therefore, it is necessary to design dual- or multi-MOFs to achieve a good adjustment of porosity and increased intrinsic activity through the synergistic effect of multi-metal components.…”

Oxygen electrocatalysts are of great importance for the air electrode in zinc-air batteries (ZABs). Owing to the high specific surface area, controllable pore size and unsaturated metal active sites, metal–organic frameworks (MOFs) derivatives have been widely studied as oxygen electrocatalysts in ZABs. To date, many strategies have been developed to generate efficient oxygen electrocatalysts from MOFs for improving the performance of ZABs. In this review, the latest progress of the MOF-derived non-noble metal–oxygen electrocatalysts in ZABs is reviewed. The performance of these MOF-derived catalysts toward oxygen reduction, and oxygen evolution reactions is discussed based on the categories of metal-free carbon materials, single-atom catalysts, metal cluster/carbon composites and metal compound/carbon composites. Moreover, we provide a comprehensive overview on the design strategies of various MOF-derived non-noble metal–oxygen electrocatalysts and their structure-performance relationship. Finally, the challenges and perspectives are provided for further advancing the MOF-derived oxygen electrocatalysts in ZABs.

“…Tan and co-workers also conducted an interesting study, they fabricated a bifunctional air electrode by the introduction of OER active Ni 3 Fe nanoparticles into ORR active Co-N-C matrix as a support derived from Co, ZIF-8 through a microwave-assisted method. [245] The resultant bifunctional electrocatalyst presented 1.54 and 0.79 V at current densities of 10 mA cm −2 (OER) and 3 mA cm −2 (ORR) respectively, constituting ΔE: 0.75 V. When Ni 3 Fe nanoparticles dispersed Co-N-C matrix was loaded as an air electrode, demonstrated a cyclic stability for a period of around 70 h. Similarly, Li et al designed a nanorod composite Co 6 Mo 6 C 2 -Co@NC by employing Mo-polydopamine@ZIF-67, wherein Co 6 Mo 6 C 2 is recognized as highly active sites for OER, whereas Co@NC serves as ORR active catalysts. [246] Consequently, Co 6 Mo 6 C 2 -Co@NC composite displayed remarkably a low overpotential of 268 mV at 10 mA cm −2 (OER), and a high half-wave potential of 0.803 V (ORR).…”

The fast growth in human population and the quick cultural advancement of human society leads to the tremendous increase in energy demand. [1] During the past, fossil fuels were used as the main energy sources, while their excessive use based on the conventional combustion technology releases excessive greenhouse gases into the environment, causing adverse impact on the sustainability of ecosystem. To cope with the challenges of stringent environmental legislations and the reliance on fossil fuels, renewable Secondary Zn-air batteries (ZABs) are recognized as one of the most promising power sources for the future with lucrative features of low cost, high energy density, eco-friendliness, and high safety. However, the widespread implementation of ZABs is still hampered by the sluggish oxygen redox reactions. Thus the deployment of cost-effective and highly efficient air electrodes to substitute precious metals (Pt/Ir), is highly challenging, however, highly desired. Zeolitic imidazolate frameworks (ZIFs) are emerging functional materials, which demonstrate several outstanding characteristics, such as high specific surface area, high conductivity, self-doped N, open pore structure, versatile compositions and favourable chemical stability. Through varying the metal/organic moiety or by employing different synthesis protocols, ZIFs with different properties could be obtained. Being adaptable, desired functionalities may be further incorporated into ZIFs through pre-treatment, in situ treatment, and post treatment. Thus, ZIFs are the ideal precursors for the preparation of variety of bi-functional air electrodes for ZABs by materials tuning, morphological control, or by materials hybridization. Here, the recent advances of ZIFs-based materials are critically surveyed from the perspective of synthesis, morphology, structure and properties, and correlated with performance indicators of ZABs. Finally, the major challenges and future prospects of ZIFs associated with ZABs are discussed.
