However, optimizing photocatalysts is challenging due to the complex interplay of factors like material composition, light absorption, and surface reactivity. Traditional trial-and-error approaches are time-consuming and resourceintensive, often requiring extensive experimentation under varied conditions. Machine learning (ML) has recently emerged as a powerful tool to accelerate photocatalyst discovery and optimization. By analyzing large datasets, ML algorithms can predict material properties, identify optimal reaction conditions, and reduce the need for exhaustive experimentation. This data-driven approach enables faster exploration of complex chemical spaces and reaction environments. This review focuses on recent advancements in integrating ML into photocatalysis, emphasizing its role in catalyst design and environmental applications. It also addresses key challenges such as data quality and model interpretability while highlighting future research directions to fully harness the potential of ML in photocatalytic systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":772,"journal":{"name":"Science China Chemistry","volume":"68 8","pages":"3415 - 3428"},"PeriodicalIF":9.7,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169064","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}

Here, we present a 3,3′-bipyridinium-based cyclophane with an inherently rigid cavity for the effective adsorption of iodine from artificial and natural seawater. This macrocycle demonstrates superior iodine adsorption capacity and reusability compared to 4,4′-bipyridinium-based cyclophane, with notably enhanced efficiencies in seawater relative to pure water. Remarkably, static adsorption in natural seawater achieved a record-high iodine uptake of 10.4 g g⁻¹, while dynamic experiments revealed iodine removal efficiency exceeding 99%. Substantial density functional theory (DFT) calculations and controlled experiments revealed that halogen ions (X⁻) and ionic concentrations critically influence adsorption performance through the formation of different [I_2<i>n</i>X]⁻ complexes, which modulate adsorption energies. X-ray crystallography of iodineloaded cyclophanes indicated that efficient iodine capture arises from multiple noncovalent interactions and the macrocycle’s loosely packed structure.

Nonetheless, several challenges persist, including the solid electrolyte interphase (SEI) instability, suboptimal ionic conductivity, inherent flammability, and an inability to operate at high voltage, significantly hindering their long-term stability and capacity retention. Given fluorine atoms’ small atomic radius and high electronegativity, fluorinated gel electrolytes (FGPEs) offer distinct advantages in mitigating these challenges. This review systematically examines the role of fluorine in enhancing the performance of GPEs, with particular emphasis on fluorine’s role in improving the SEI composition in GPEs. Additionally, the review elucidates the mechanism of thermal runaway in LMBs and investigates fluorine’s contribution to enhancing the flame retardancy of these batteries. The article also details the role of fluorinated components in facilitating lithium-ion transport and evaluates the suitability of fluorinated gel polymer electrolytes for high-voltage applications. Finally, the review elaborates on design strategies for advancing FGPEs and underscores their potential to address critical challenges in lithium metal battery technology.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":772,"journal":{"name":"Science China Chemistry","volume":"68 10","pages":"4712 - 4732"},"PeriodicalIF":9.7,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284400","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}
