“…The phase structures of catalysts were analyzed by XRD (Figure a,b). Fe-ZIF-8 exhibited XRD patterns similar to those of ZIF-8, indicating that Fe incorporation has no influence on the phase structure of ZIF-8. Apparently, the XRD peaks of Fe-ZIF-8@PPy are composed of both Fe-ZIF-8 and PPy components, indicating a successful synthesis of the hybrid.…”

One-dimensional metal/N-doped carbons have exhibited promise for use as efficient catalysts of the oxygen reduction reaction (ORR). In this work, Fe,Ndoped carbon nanotubes (Fe-NC@NCNT) are developed by pyrolyzing the precursor/template of a polypyrrole (PPy) nanotube-anchored Fe/Zn-based zeolite imidazole framework. Thanks to the hierarchical tubular nanostructure, high electronic conductivity, and abundant Fe-based species (Fe-N x sites and Fe/Fe 3 C nanoparticles), the designed electrocatalyst exhibits a catalytic property comparable to that of commercial Pt/C. Specifically, the Fe-NC@NCNT catalyst undergoes a fourelectron ORR pathway with an onset potential of 0.96 V and a half-wave potential of 0.88 V versus reversible hydrogen electrode, a small Tafel slope of 60.0 mV dec −1 , remarkable long-term cycle durability, as well as strong alcohol tolerance in an alkaline electrolyte. When applied to the air-electrode catalyst of rechargeable zinc−air batteries, the

Single‐atom catalysts (SACs) have been one of the frontiers in the field of catalysis in recent years owing to their high atomic utilization and unique electronic structure. To facilitate the practical application of single‐atom, it is vital to develop a sustainable, facile single‐atom preparation method with mass production potential. Herein, a universal one‐step electrochemical synthesis strategy is proposed, and various metal–organic framework‐supported SACs (including Pt, Au, Ir, Pd, Ru, Mo, Rh, and W) are straightforwardly obtained by simply replacing the guest metal precursors. As a proof‐of‐concept, the electrosynthetic Pt‐based catalysts exhibit outstanding activity and stability in the electrocatalytic hydrogen evolution reaction (HER). This study not only enriches the single‐atom synthesis methodology, but also extends the scenario of electrochemical synthesis, opening up new avenues for the design of advanced electro‐synthesized catalysts.

“…Zeolitic-imidazolate-frameworks-8 (ZIF-8) have been demonstrated as effective precursors or templates for constructing nitrogen-doped single-atom catalysts (SACs) through hightemperature pyrolysis, taking advantage of their abundant nitrogen species, tunability of metal nodes, facile fabrication, and high structural stability. [1][2][3] Over the past decade, ZIF-8derived SACs have been widely used in various electrocatalytic reactions, including the hydrogen evolution reaction (HER), 4 oxygen evolution reaction (OER), 5,6 oxygen reduction reaction (ORR), [7][8][9][10] nitrogen reduction reaction (NRR), 11,12 and CO 2 reduction reaction (CO 2 RR). [13][14][15][16] A couple of structural modications have been applied in ZIF-8-derived SACs to improve their electrocatalytic properties, for example, increasing the loading of single atoms, 17 adjusting the metal-N structures in the SACs, [18][19][20] modifying the electron structures of the single atoms, 21,22 and constructing bimetallic atomic pairs, [23][24][25][26][27] to name just a few.…”
