However, the limited specific capacity of commercial graphite anodes can no longer meet the growing demands of high-energy devices, driving the search for alternative anode materials and beyond‑lithium battery systems with higher energy densities and longer lifespans. Tin-based chalcogenides (Sn<sub>x</sub>M<sub>y</sub>, where M = O, S, Se, or Te) have attracted considerable attention due to their unique physicochemical properties, enabling diverse applications in energy storage and conversion. They are particularly promising for alkali metal-ion batteries, offering high theoretical capacity, low cost, natural abundance, and environmental compatibility. In addition, their strong polarity, high catalytic activity, and favorable affinity render them excellent functional materials for metal‑sulfur and metal batteries, where they can act as hosts, skeletons, or catalysts. Despite these advantages, their practical deployment is limited by severe volume expansion, low electrical conductivity, structural instability, and restricted active sites of individual materials. Recent efforts have sought to overcome these issues through heterointerface engineering, which leverages interfacial effects to enhance mechanical integrity and electronic properties. This review critically evaluates advances in heterostructured tin-based chalcogenides for rechargeable batteries, focusing on their fundamental properties, structural benefits, synthesis strategies, and electrochemical behaviors. Finally, we highlight persistent challenges and propose future research directions to accelerate the development of next-generation high-performance tin-based materials for rechargeable batteries.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"702 ","pages":"Article 138909"},"PeriodicalIF":9.7,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145045678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To effectively degrade the refractory benzene rings of tetracycline (TC), it is crucial to control strong peroxymonosulfate (PMS)-activated radicals. To tackle these issues, a NiFe-silicate layered double hydroxide (NiFe-SiO₃ LDH) was synthesized using industrial waste montmorillonite as a silicon source through hydrothermal etching and co-precipitation. This approach promotes both waste valorization and the advancement of catalyst development. Comprehensive analyses (TEM, XRD, FT-IR, BET, XPS) showed that silicate doping triggers a “structural optimization- structural destabilization” mechanism. Adding SiO₃<sup>2−</sup> made the pores smaller, down to 4.79 nm, and increased the surface area to 158.0 m<sup>2</sup>·g<sup>−1</sup>, which helped mass transfer. It also changed the electronic structure by raising Ni<sup>2+</sup> oxidation states (Δ ≈ 0.12 eV). Together, these effects synergistically improved PMS activation. Consequently, the optimized catalyst achieved 85.3 % TC mineralization within 20 mins with a rate constant of 0.13 min<sup>−1</sup>, surpassing CoFe-based oxides and FeS benchmarks. However, excessive SiO₃<sup>2−</sup> caused pore blockage and charge inversion, leading to catalytic deactivation. In-situ characterization (UV–vis, EPR) and HPLC-MS revealed a multi-pathway mechanism: Hydroxyl radicals (·OH) facilitate benzene ring epoxidation, whereas superoxide radicals (·O₂<sup>−</sup>) and singlet oxygen (<sup>1</sup>O₂) can promote heteroatom oxidation.
