“…The atomic dispersion of metal can exploit the 100 % usage of active sites for various energy related electrochemical reactions [32] . Despite the progress in other precursors to prepare single‐atom catalysts (SACs), the MOF‐derived SACs have been verified to display greater performance for electrocatalysis [32a,33] . The proficient formation of atomically dispersed metal sites on carbon materials through changing MOFs’ precursors with N‐containing organic ligands and large Zn amount are favored [33b] .…”

The increasing demands of energy and environmental concerns have motivated researchers to cultivate renewable energy resources for replacing conventional fossil fuels. The modern energy conversion and storage devices required high efficient and stable electrocatalysts to fulfil the market demands. In previous years, we are witness for considerable developments of scientific attention in Metal‐organic Frameworks (MOFs) and their derived nanomaterials in electrocatalysis. In current review article, we have discussed the progress of optimistic strategies and approaches for the manufacturing of MOF‐derived functional materials and their presentation as electrocatalysts for significant energy related reactions. MOFs functioning as a self‐sacrificing template bid different benefits for the preparation of metal nanostructures, metal oxides and carbon‐abundant materials promoting through the porous structure, organic functionalities, abundance of metal sites and large surface area. Thorough study for the recent advancement in the MOF‐derived materials, metal‐coordinated N‐doped carbons with single‐atom active sites are emerging candidates for future commercial applications. However, there are some tasks that should be addressed, to attain improved, appreciative and controlled structural parameters for catalytic and chemical behavior.

“…[21][22][23][24][25][26][27][28][29][30][31][32][33] Among the various catalysts studied, the metal-N-doped carbons (M-N-C) are categorically active catalysts for ORR for PEM fuel cells (PEMFCs). [34,35] New unanimity in this arena is that ORR active sites must be made up of fully exposed N-coordinated transition metal centers with an improved density of dispersed active sites. [36][37][38][39] The constitution of undesired agglomerated metal clusters thus remains the main barrier to further improve the ORR performance.…”

Recent progress in synthetic strategies, analysis techniques, and computational modeling assist researchers to develop more active catalysts including metallic clusters to single-atom active sites (SACs). Metal coordinated N-doped carbons (M-N-C) are the most auspicious, with a large number of atomic sites, markedly performing for a series of electrochemical reactions. This perspective sums up the latest innovative and computational comprehension, while giving credit to earlier/pioneering work in carbonaceous assembly materials towards robust electrocatalytic activity for proton exchange membrane fuel cells via inclusive performance assessment of the oxygen reduction reaction (ORR). M-N x -C y are exclusively defined active sites for ORR, so there is a unique possibility to intellectually design the relatively new catalysts with much improved activity, selectivity, and durability. Moreover, some SACs structures provide better performance in fuel cells testing with long-term durability. The efforts to understand the connection in SACs based M-N x -C y moieties and how these relate to catalytic ORR performance are also conveyed. Owing to comprehensive practical application in the field, this study has covered very encouraging aspects to the current durability status of M-N-C based catalysts for fuel cells followed by degradation mechanisms such as macro-, microdegradation, catalytic poisoning, and future challenges.
