摘要

Noble metal-based electrocatalysts (NMECs), particularly those with activesites at the nano or atomic level, are indispensable in heterogeneouscatalysis, which has attracted considerable research interests, especiallyin the energy communities. Due to the enormous inherent merits, suchas ultrahigh surface area, tunable atomic structure, and diverse chemicaltailorability, metal-organic frameworks (MOFs) have been proposed as idealcandidates for creating efficient and programmable NMECs. In this review,from an interdisciplinary opinion,the recent progresses on the syntheticprinciples and catalytic site design protocols for the atomically structuredMOFs and their derivatives are comprehensively discussed. Particularly, it isdedicated to summarizing the modulation strategies on creating the catalyticcenters and bond microenvironments of MOFs-based NMECs, including thesingle-atom, dual-atom, cluster, and nanoparticle engineering. Furthermore,the critical mechanisms of how the structures of MOFs-based NMECs affectthe corresponding electrochemical behaviors is outlined and disclose thecritical essences for their future applications. Finally, the current developments,challenges, and perspectives for engineering the atomically structuredMOFs-based NMECs are discussed to inspire the broad utilization ofMOFs-based NMECs-equipped catalysts in energy conversion, which offerscutting-edge guidance for future prosperity in developing efficient NMECs.
