In this study, we introduce a highly effective non-metallic iodine single-atom catalyst (SAC), referred to as I-NC, which is strategically confined within nitrogen-doped carbon (NC) scaffold. This configuration features distinctive C-I coordination that optimizes the electronic structure of nitrogen-adjacent sites. As result, arrangement enhances electron transfer from peroxymonosulfate (PMS) active sites, particularly electron-deficient carbon. followed by deprotonation process generates radical (SO5•-). Subsequently, SO5•- undergoes disproportionation reaction, leading production singlet oxygen (1O2). Furthermore, energy barrier for rate-limiting step generation in I-NC significantly lower at 1.45 eV, compared 1.65 eV NC reduction effectively overcomes kinetic obstacles, thereby facilitating an enhanced 1O2. Consequently, exhibits remarkable catalytic efficiency and unmatched reactivity PMS activation. leads accelerated degradation pollutants, evidenced relatively high observed rate constant (kobs ~ 0.436 min-1) other metallic SACs. study offers valuable insights into rational design SACs, showcasing their promising potential Fenton-like reactions water treatment applications.

Abstract Micropollutants (MPs) pose a significant threat to global water environments, necessitating advanced treatment technologies. Distributed electrochemical systems utilizing electrified membranes (EMs) show promise but face challenges due unclear mass transfer and reaction mechanisms within membrane pores of varying sizes surface chemistry. This review examines the interplay between spatial confinement, transfer, chemical reactions in EMs, focusing on reactive species (RSs), EM‐MPs system evolution, phenomena across pore from microns sub‐nanometer scales. Despite advances RS research, coherent mechanistic understanding MP degradation under confinement remains elusive, particularly extreme where deviate bulk behavior. Gaps knowledge stem complex dynamics, thermodynamics kinetics, need for detailed theoretical describe effects. summarizes generation detection methods RSs, outlines progress EM operational modes, elucidates how impacts both reactions. Future research shall focus precise identification quantitative regulation optimization processes relation RSs MPs, investigation active sites energetic barriers confined environments.

Abstract Single‐atom catalysts (SACs) have garnered significant attention in the applications of environmental remediation based on Fenton‐like systems. Current research single‐atom catalysis often emphasizes catalytic activity and mechanism regulation, while paying limited to simultaneous enhancement both stability—a critical factor for practical scale‐up SACs. This review systematically summarizes recent advances synchronization strategies improving stability catalysis, with a focus design principles mechanisms four key strategies: coordination engineering, confinement effects, carrier substitution, module design. To best knowledge, this represents first comprehensive from perspective concurrent optimization stability. Additionally, auxiliary role machine learning lifecycle assessment (LCA) is evaluated advancing these strategies. By investigating interplay among different support materials, configurations, reaction environments, as well enlarged modules, factors governing stability/activity SACs are highlighted, future directions proposed developing next‐generation high efficiency long‐term durability remediation.
