Abstract Numerous in situ characterization studies have focused on revealing the catalytic mechanisms of single‐atom catalysts (SACs), providing a theoretical basis for their rational design. Although research is relatively limited, stability SACs under long‐term operating conditions equally important and prerequisite real‐world energy applications, such as fuel cells water electrolyzers. Recently, there has been rise destabilization regeneration SACs; however, timely comprehensive summaries that provide catalysis community with valuable insights directions are still lacking. This review summarizes recent advances strategies SACs, specifically highlighting various state‐of‐the‐art techniques employed studies. The factors induce identified by discussing failure active sites, coordination environments, supports, reaction scenarios. Next, primary introduced, including redispersion, surface poison desorption, exposure subsurface sites. Additionally, advantages limitations both ex discussed. Finally, future proposed, aimed at constructing structure–stability relationships guiding design more stable SACs.

Nitrogen-doped carbon-supported Fe catalysts (Fe-N-C) with Fe-N4 active sites hold great promise for the oxygen reduction reaction (ORR). However, fine-tuning structure of to enhance their performance remains a grand challenge. Herein, we report an innovative design strategy promote ORR activity and kinetics by engineering Lewis acidity, which is achieved tuning spatial coordination geometry. Theoretical calculations indicated that Fe1-N4SO2 (with axial –SO2 group bonded Fe) offered favorable acidity ORR, leading optimized adsorption energies key intermediates. To implement this strategy, developed molecular-cage-encapsulated synthesize single-atom site catalyst (SAC) sites. In agreement theory, Fe1-N4SO2/NC demonstrated outstanding in both alkaline (E1/2 = 0.910 V 0.1 M KOH) acidic media 0.772 HClO4), surpassing commercial Pt/C traditional SACs Fe1-N4 or planar S-coordinated Fe1-N4-S Moreover, newly showed application potential quasi-solid-state Zn–air batteries, delivering superior across wide temperature range.

High-entropy metal–organic frameworks (HE-MOFs) offer immense potential in electrocatalysis due to their diverse metallic compositions and high densities of active sites. Integrating bimetallic single-atom catalysts (SACs) with HE-MOFs for enhanced oxygen evolution reaction (OER) performance remains challenging. Here, we stabilize atomically dispersed Ru Mo amorphous HE-MOF nanosheets (HE(Ru,Mo)-MOFs) via situ-formed high-entropy oxides, elucidating the deprotonation mechanism. Evidence supports presence high-density O-bridged dual-atom The multimetallic composition induces electronic redistribution balances oxidation state metal sites, enhancing intrinsic OER activity. HE(Ru,Mo)-MOFs exhibit low overpotentials 267 mV@10 mA cm–2 266 alkaline freshwater industrial wastewater, respectively, exceptional durability surpassing that commercial RuO2 catalysts. Mechanistic insights reveal atomic dispersion facilitates rapid charge transfer intermediate transformation, promising advanced energy conversion.
