The experimental results demonstrated that the incorporation of single-atom Fe significantly enhanced the photocatalytic activity, attaining a 99.05% HCHO removal rate (residual concentration of 0.43 ppm after 1 h), outperforming most TiO₂-based materials. The fundamental enhancement mechanism was elucidated using in situ DRIFTS spectroscopy, EPR, TOF-SIMS, and DFT calculations. The results revealed that single Fe atoms and oxygen vacancies serve as active sites and electron reservoirs, thereby enhancing molecular oxygen activation by promoting electron transfer to the π-antibonding orbital (π_2p^*) of O₂. Consequently, this process generated highly reactive monoatomic oxygen anions (O⁻) as the dominant reactive oxygen species. Further mechanistic analysis has confirmed that the O⁻ species can oxidize HCHO through a DOM intermediate pathway, ultimately mineralizing it into CO₂ and H₂O. This study elucidated the pivotal role of O⁻ radicals in the deep oxidation of HCHO and provided novel theoretical insights and strategic guidance for the design of highly efficient TiO₂-based air-purification materials.</p>\u0000 </div>","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 7","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with pristine BiOI and the corresponding covalent organic frameworks (COFs), both composites exhibited markedly enhanced degradation rate under visible-light irradiation for 90 min (TC: 96.1% for COF-C₄N@BiOI-55 and 95.1% for COF-TpMA@BiOI-55; OTC: 93.8% for COF-C₄N@BiOI-55 and 94.8% for COF-TpMA@BiOI-55). Structural characteristics indicated that the BiOI crystalline phase was well preserved after hybridization and that strong interfacial interaction is established. The improved photoelectrochemical properties suggested suppressed charge recombination, along with promoted interfacial transfer and separation of photogenerated carriers. Reactive-species identification confirmed ∙O₂⁻ as the dominant species, while ∙OH and h⁺ contributed synergistically to the oxidation process. Work-function analysis together with XPS evidence demonstrated electron enrichment on BiOI and a built-in potential that promotes directional charge transfer. A Z-scheme-like charge-transfer channel is proposed.

They are engineered to merge different materials into a single, lightweight structure. However, their recycling is challenging because the layers are strongly bonded and chemically heterogeneous. As a result, multilayer packages (MLPs) often bypass recycling streams, causing environmental pollution and resource depletion. A potential long-term solution is represented by disassembly processes that separate layers and direct them into single-polymer streams. This review examines studies on separation technologies and categorizes them by their dominant mechanism of action. Delamination techniques chemically remove or deactivate bonding layers, whereas selective dissolution-precipitation (SDP) uses polymer-solvent thermodynamic windows to dissolve and recover polymer layers sequentially. For solvent selection, we consolidated Hansen Solubility Parameters to produce polymer solvent compatibility and distance maps for common polymers. Additionally, a detailed comparison is made of recovery outcomes, technology readiness levels, and their impacts on recyclate purity and food-contact safety. Structural separation offers a feasible approach to reintroducing post-consumer MLPs into mechanical recycling, provided solvent management, contamination control, and regulatory compliance are properly managed.

In this work, a 0D/2D FeCoS₂/ZnCdS Schottky junction was prepared by physically blending FeCoS₂ nanoparticles with ZnCdS nanosheets, which enabled efficient PHE. The bimetallic sulfide FeCoS₂ not only increases the active sites of the composite and lowers the hydrogen evolution overpotential, but also enhances the light-harvesting capability through its interfacial interaction. DFT calculation results indicate that FeCoS₂ possesses metallic-like properties, enabling the formation of a Schottky junction between FeCoS₂ and ZnCdS. Moreover, due to the work function difference, electrons flow from ZnCdS to FeCoS₂, forming a Schottky barrier and a built-in electric field at the interface. This electric field drives rapid electron transfer and suppresses electron backflow. More importantly, the metal-like nature of FeCoS₂ is conducive to the efficient migration of interfacial electrons. The best PHE rate of 14.57 mmol g⁻¹ h⁻¹ is therefore shown by the optimized 15%FeCoS₂/ZnCdS, which is increased 5.1-fold compared to pure ZnCdS (2.86 mmol g⁻¹ h⁻¹).
