The electrochemical carbon dioxide reduction reaction (CO2RR) represents a promising approach for achieving CO2 resource utilization. Carbon-based materials featuring single-atom transition metal-nitrogen coordination (M-Nx) have attracted considerable research attention due to their ability maximize catalytic efficiency while minimizing metal atom usage. However, conventional synthesis methods often encounter challenges with particle agglomeration. In this study, we developed Ni-doped polyvinylidene fluoride (PVDF) fiber membrane via electrospinning, subsequently transformed into nitrogen-doped three-dimensional self-supporting Ni catalyst (Ni-N-CF) through controlled carbonization. PVDF was partially defluorinated and crosslinked, the single chain is changed reticulated structure, which ensured that structure did not collapse during carbonization effectively solved problem of runaway M-Nx composite in high-temperature pyrolysis process. Grounded X-ray photoelectron spectroscopy (XPS) absorption fine (XAFS), nitrogen coordinates nickel atoms form Ni-N keeps low oxidation state, thereby facilitating CO2RR. When applied CO2RR, Ni-N-CF demonstrated exceptional CO selectivity Faradaic (FE) 92%. unique architecture addressed traditional electrode instability issues caused by detachment. These results indicate tuning local atomically dispersed Ni, original inert sites can be activated efficient centers. This work provide new strategy designing high-performance catalysts structurally stable electrodes.

Abstract Single‐atom site electrocatalysts (SACs), with maximum atom efficiency, fine‐tuned coordination structure, and exceptional reactivity toward catalysis, energy, environmental purification, have become the emerging frontier in recent decade. Along significant breakthroughs activity selectivity, limited stability durability of SACs are often underemphasized, posing a grand challenge meeting practical requirements. One pivotal obstacle to construction highly stable is heavy reliance on empirical rather than rational design methods. A comprehensive review urgently needed offer concise overview progress stability/durability, encompassing both deactivation mechanism mitigation strategies. Herein, this first critically summarizes degradation induction factors at atomic‐, meso‐ nanoscale, mainly based but not oxygen reduction reaction. Subsequently, potential stability/durability improvement strategies by tuning catalyst composition, morphology surface delineated, including robust substrate metal‐support interaction, optimization active stability, fabrication porosity modification. Finally, challenges prospects for discussed. This facilitates fundamental understanding provides efficient principles aimed overcoming difficulties beyond.
