The glycerol oxidation reaction is characterized by mild reaction conditions and relatively simple products, making it a widely utilized method for glycerol conversion and one of the most promising industrial approaches. In this study, we prepared black titanium dioxide-supported platinum catalysts with different morphology. Different catalysts were synthesized by altering the morphology of the support and the reduction temperature of the support, which exhibited distinct activities and performance in the catalytic oxidation of glycerol to glyceric acid under alkali-free conditions. The evaluation of the catalysts revealed that when flaky black titanium dioxide (F-B-TiO2) is employed as a support, the catalyst Pt/F-B-TiO2 (600 °C), reduced at 600 °C, demonstrates the best catalytic performance. Characterization results indicate that the Ti3+ content in the flaky (F-B-TiO2) support is higher compared to other morphologies. Additionally, at a calcination temperature of 600 °C, the Pt° content is maximized among the synthesized catalysts. Based on the experimental and characterization results, the catalytic performance is collaboratively influenced by the presence of Ti3+ and Pt0.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500175"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810088","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}

However, the mismatch between the energy levels of metal ions and organic ligands leads to a weak PL emission. Herein, this study presents a pressure-treated strategy aimed at achieving efficient green PL in Tb2(BDC)3(H2O)4 MOF. Compared to the initial intensity, the PL intensity is enhanced eightfold below 3.1 GPa. Intriguingly, the PL intensity of pressure-treated sample is amplified by 2.5-fold compared to the initial state, and the green emission monochromaticity is maintained. Experiments and calculations reveal that the enhanced hydrogen bonds are retained to the ambient conditions after pressure treatment. They lock the conjugated configuration formed between the planes of carboxyl group and benzene ring, facilitating the intersystem crossing. The reduced distances between metal ions and organic ligands drive the ligand-to-metal energy transfer process. This finding provided significant insights into structure-property relationship of Tb2(BDC)3(H2O)4, offering a new platform for boosting emission enhancement in Ln-MOFs.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401784"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810350","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}

By merging these two classes in so-called extended tetrathiafulvalenes, new physico-chemical characteristics emerge. Here in this study, we summarize the properties of such PAH-extended TTFs for which the PAH core incorporates five-membered carbo-cyclic rings together with six-, seven-, and/or eight-membered rings. A key structural motif of these molecules is the planar 2-(1H-inden-1-ylidene)-1,3-dithiole unit. Fusing two such units directly together or via various one- or two-dimensional PAH scaffolds has during the past decade provided a large selection of planar, twisted, or curved extended TTFs. Strong associations of radical cations are in some cases obtained, corresponding to redox-controlled self-assembly in solution, and these associations have allowed for the ready generation of semi-conducting salts by electrocrystallization. Some molecules exhibit remarkable multiredox behavior and can reversibly reach high cationic states, and, in some cases, also anionic states. Several structural examples also reveal how closed-shell versus open-shell characters of the dication states can be controlled by the nature of the PAH core, particularly by the number of Clar sextets within the core.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202500356"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809992","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 order to improve separation efficiency and selectivity, computational simulation could elucidate interaction mechanisms and analyze potential adsorption/desorption processes, providing a theoretical foundation for the optimization and design of separation materials. Recently, computational simulation has become an indispensable and crucial mean in separation science for analytical chemistry. Using various simulation software, researchers could investigate the structures, properties, and performance of separation materials at multiple levels and scales. In this review, we summarize the applications of computational simulations in the field of separation science, focusing on the separation of polar molecules, geometric isomers, enantiomer compounds, and post-translationally modified peptides. These calculation methods include quantum chemistry, molecular docking, molecular dynamics simulations, high-throughput screening, and machine learning.
