Pickering emulsions offer an effective platform for achieving these goals. A key challenge is developing simple, efficient methods that enable fast reactions, easy product separation, catalyst recovery, and emulsifier reuse. Herein, a light-switchable oil-in-water (O/W) Pickering emulsion composed of a spiropyran-based ionic liquid surfactant, UiO-66-NH2, toluene, and water is presented. The system can reversibly transition between demulsification and emulsification under alternating visible and ultraviolet light. This feature enables the O/W Pickering emulsion to function as a precisely controlled interfacial catalysis reactor for synthesizing hydrophilic products via Click reaction. The catalytic platform is highly efficient, requiring minimal catalyst loading. It reduces activation energy from 33.6 to 8.5 kJ mol-1, a fourfold decrease, and improves conversion efficiency by more than 50%. Under visible light, the spiropyran structure in water shifts from a hydrophilic open-ring MC form to a hydrophobic closed-ring SP configuration. This structural change enhances the adsorption capacity of the spiropyran-based ionic liquid surfactant on UiO-66-NH2 and increases its partition coefficient between toluene and water. At the same time, the surfactant's surface activity decreases, which explains the light-responsive phase behavior of Pickering emulsions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501618"},"PeriodicalIF":6.6,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a bioinspired strategy is reported to enhance the photocatalytic performance of COFs by introducing an ortho-positioned arrangement of enol (OH) and imine (N) groups. Through rational molecular engineering, a concerted proton-coupled electron transfer (PCET) pathway is established, which facilitates the efficient separation and transfer of photoexcited charge carriers, thereby dramatically enhancing H2O2 production from water and oxygen. The TbDO COF, featuring the PCET pathway, demonstrates superior performance, achieving a remarkable H2O2 production rate of 7265 μmol g-1 h-1 in a nonsacrificial system, surpassing COFs with similar structure but lacking this pathway. This study advances the design of COFs and opens new avenues for sustainable solar-to-chemical energy conversion.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501760"},"PeriodicalIF":6.6,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Constructing efficient Schottky heterojunctions with vacancy defects can be a productive approach for achieving photooxidation of 5-hydroxymethylfurfural (HMF). Herein, sulfur vacancy (Vs) defect-enriched ZnIn2S4 is combined with Ti3C2Tx MXene (Vs-ZIS/MX) containing Schottky heterojunctions via self-assembly to form photocatalysts for efficient oxidation of HMF to 2,5-diformylfuran (DFF) under air-ambient conditions. HMF conversion of 87.3% with 72.9% DFF selectivity is obtained by the Vs-ZIS/MX heterojunction photocatalyst under visible light (420 nm < λ <780 nm, 2 h). Density functional theory calculations reveal that the Schottky heterojunction and regulated S vacancies enhance the electronic coupling and lower HMF adsorption energy, establishing a directional electron transfer channel from Vs-ZIS to MXene and an enhanced built-in electric field. Extended X-ray absorption fine structure spectroscopy shows that a stable metal (Zn)O bond coordination is formed between Vs-ZIS and MXene, and the enrichment of local electrons at S vacancy defects sites and metal-O coordination makes it possible to extract the delocalized electrons from ZIS to MXene. This work demonstrates a method to modulate the electron cloud density and enhance transport with a built-in electric field on photogenerated carriers for catalytic conversion of organic alcohols.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501504"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past 5 years, Li-NRR research has grown significantly, leading to rapid advancements in ammonia production rates and Faradaic efficiency. This review focuses on the recent advancements in Li-NRR, with a particular emphasis on strategies aimed at improving system stability. Various strategies to enhance the stability of Li-NRR systems are categorized and analyzed, including the optimization of proton carriers, the design of favorable solid-electrolyte interphases, and the regulation of anodic reactions to prevent electrolyte decomposition. The review also highlights the growing importance of materials selection and reaction conditions, such as electrolyte composition and electrode design, in achieving high Li-NRR system stability. Despite rapid progress, several current challenges are identified, and future directions for research to create more robust and sustainable Li-NRR systems are proposed. This work aims to provide insights into the critical factors that drive the performance and stability of Li-NRR and to inspire future efforts toward the development of efficient and scalable ammonia synthesis technologies.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500674"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a thermally activated carbon cloth (CC450) that simultaneously addresses iodine confinement and reaction kinetics through precisely engineered hierarchical porosity is reported. By optimizing oxidative calcination at 450 °C in air, CC450 develops a unique pore structure with nanopores for strong I3 - adsorption and interconnected macropores for rapid ion transport, while maintaining the intrinsic conductivity and flexibility of CC. The CC450 cathode achieves an exceptional balance of performance metrics: high areal capacity, ultralow self-discharge (3.05% in 24 h), and outstanding cycling stability (94.63% capacity retention over 1000 cycles), which represents the best-reported performance for binder-free carbon electrodes in Zn-I2 batteries. Mechanistic studies reveal that CC450's 12-fold reduction in charge-transfer resistance and low activation energy for I- oxidation stem from its optimal surface chemistry and pore hierarchy. The self-discharge tests and UV-vis spectroscopy confirm efficient iodine shuttle suppression. Unlike complex nanomaterial-based hosts, CC450 is fabricated through a scalable ambient-air process, offering immediate industrial relevance. This work provides critical insights into pore-engineered carbon hosts for metal-iodine batteries and establishes a generalizable strategy for achieving high-energy, long-life energy storage systems.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501455"},"PeriodicalIF":6.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
