SnS2, a non-precious metal sulfide semiconductor, has great potential in photocatalytic CO2 reduction due to its unique physicochemical properties. However, low electrical conductivity and susceptibility to aggregation of pure SnS2 lead to a high charge recombination rate and hinder the photocatalytic efficiency. In this study, we report that single/few-layered MXene induces ordered growth of SnS2 through electrostatic interactions and in situ solvothermal heating. Interconnected SnS2 nano-array with abundant sulfur vacancies was successfully prepared on MXene surface (Vs-SnS2/MXene). This unique structure promotes the separation and migration of photogenerated charges and effectively inhibits electron-hole recombination. Compared with pure SnS2, the average lifetime of photogenerated charges in Vs-SnS2/MXene increased by 45.6 %. Meanwhile, its CO production rate reached 47.6 μmol⋅g-1⋅h-1, which was 2.6-fold higher than that of pure SnS2 (18.3 μmol⋅g-1⋅h-1), and showed excellent photocatalytic CO2 reduction performance in gas-solid-phase reaction mode. In addition, Vs-SnS2/MXene also showed excellent stability. The results showcased the transformative potential of integration strategies for designing high-performance photocatalytic systems.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500086"},"PeriodicalIF":3.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biomass-derived carbon dots (B-Cdots) have gained significant attention for their potential to address this challenge. Utilizing greener routes for the large-scale synthesis of B-Cdots is not only eco-friendly and cost-effective but also promotes sustainability. This review highlights various synthesis methods for B-Cdots, including microwave-assisted, hydrothermal, and pyrolysis-based carbonization processes. It also explores their electrochemical applications in supercapacitors, lithium-ion batteries, sodium-ion batteries, and other energy storage devices, along with recent advancements in the field. The fabrication of electrodes using B-Cdots offers several advantages, such as tunable chemical and physical properties, porous structures, efficient heteroatom doping, and excellent electrical conductivity. These attributes make B-Cdots highly attractive for energy storage applications. Overall, this review emphasizes the critical role of sustainable materials in shaping the future of energy storage technologies.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500094"},"PeriodicalIF":3.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several efforts have been dedicated to establishing international restrictions on their use, the definition of what qualifies as a PFAS remains a matter of debate among scientists, regulatory agencies, and industry. This article provides a brief overview of the different approaches proposed and adopted to date for identifying and grouping of these pollutants, either based on common structural motifs or on the combination of multiple factors, including functional uses, degradation behavior, physicochemical properties, and toxicity. The diversity and complexity of PFAS substances suggests the need of a multifaceted classification system that can guide regulatory efforts, risk assessment, and environmental monitoring through standardized criteria accepted on an international scale. A pivotal role in establishing a universal definition of PFAS will be played by the International Union of Pure and Applied Chemistry (IUPAC), which is currently supporting a project on the terminology and classification of these chemicals.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500127"},"PeriodicalIF":3.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we combined machine learning and data analysis with experimental work to investigate this effect. Machine learning (using a decision tree model) identified copper particle size, average pore diameter, reduction time, surface area, and metal loading content as the most impactful features for catalyst design. However, experimental results indicated that nitrogen doping on graphene support improved the space-time yield by up to four times compared to pristine graphene. This improvement is attributed to nitrogen's role in lowering the catalyst's reduction temperature, enhancing its quality under identical reduction conditions, though nitrogen itself does not directly affect methanol formation. Moreover, machine learning provided insights into the critical features and optimal conditions for catalyst design, demonstrating significant resource savings in the lab. This work exemplifies the integration of machine learning and experimentation to optimize catalyst synthesis and performance evaluation, providing valuable guidance for future catalyst design.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500011"},"PeriodicalIF":3.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
