In recent years, iron-based single-atom catalysts (Fe-SACs) have emerged as promising alternatives to conventional heterogeneous catalysts, offering atomically dispersed active sites that combine the stability of heterogeneous systems with the selectivity of homogeneous catalysis. This review provides a comprehensive overview of Fe-SACs, with a particular focus on their synthesis, structural engineering, and stabilization on a wide range of supports, including carbon materials, metal–organic frameworks, metal oxides, and layered substrates. Special emphasis is placed on the interfacial chemistry, coordination environment, and electronic structure of isolated Fe sites, which critically influence catalytic performance. In addition, the review systematically explores the diverse environmental applications of Fe-SACs, including pollutant degradation, CO₂ conversion, Fenton-like reactions, oxygen reduction reactions, and green organic transformations. The role of theoretical calculations, particularly density functional theory, is highlighted in understanding active site behavior and reaction mechanisms, while emerging artificial intelligence and machine-learning approaches are discussed for their potential to accelerate catalyst design and optimization. Finally, current challenges, scalability considerations, and future research directions are outlined, providing a forward-looking perspective for the development of next-generation Fe-SACs in sustainable catalytic science.</p>","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 19","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While abundant lithium exists in salt-lake brines, its efficient extraction remains challenging, highlighting the need for highly selective adsorbents. Herein, a stable zirconium-based metal-organic framework (Zr-MOF) was utilized as a platform to construct an adsorbent for Li⁺ by incorporating 4′-carboxybenzo-12-crown-4 (CE) onto [Zr₆O₈] cluster via ligand exchange. Zr-MOF not only provides abundant anchor sites for CE molecules but also creates efficient mass transport channels. The resulting CE@Zr-MOF exhibits excellent Li⁺ adsorption capacity, reaching up to 33.6 mg g⁻¹, and maintains high selectivity even in the presence of elevated concentrations of competing ions. Mechanistic studies reveal that the well-defined cavities of CE offer ideal binding sites for Li⁺, while steric hindrance reduces the affinity for interfering ions, thus enhancing selectivity. Moreover, Zr-MOF not only serves as a carrier but also enhances the adsorption capacity of CE through charge interactions.

Herein, with the azobenzene tridentate ligand, we synthesized two types of hypervalent lead compounds where lead has different oxidation states. We evaluated the influence of different oxidation states on the electronic structure of the π-conjugated framework. From optical measurements and theoretical investigation, it was revealed that the intramolecular nitrogen–lead (N–Pb) interactions and the molecular orbitals of the azobenzene skeleton should be varied. The hypervalent lead(II) compound exhibited higher affinity (Lewis acidity) to the coordinating reagents than the hypervalent lead(IV) compound. Furthermore, we found that the extensive accessible space around the hypervalent element center increases in binding constants for additional bulky ligands such as ethylenediamine. We demonstrate here that changes in the oxidation state of hypervalent lead can induce drastic perturbations in the π-conjugated system, and furthermore, clear changes were observed in the optical properties and molecular coordination behaviors.
