In this work, a mesoporous molecular sieve with graphite carbon-coated Co NPs (Co@CN/Al-MCM-41) was successfully synthesized by vacuum-injecting the precursor solution into the MCM-41 molecular sieve and subsequent calcination. Using Co@CN/Al0.1-MCM-41 as the catalyst, the selective hydrogenation of FF to FOL achieved a conversion rate of 91.2% under mild conditions at 120 °C, which is 2.85 times higher than that of Al-free Co@CN/MCM-41, with an FOL selectivity of 97.2%. The experimental results revealed a strong correlation between FF conversion and the Si/Al ratio of MCM-41 molecular sieve. Increasing the Al species content facilitated the formation of more Co NPs active sites because of the strong electrostatic interaction, thereby promoting the activation of FF and hydrogen and enhancing the catalytic activity of Co@CN/Al0.1-MCM-41. Additionally, Co@CN/Al0.1-MCM-41also exhibited stable performance over five consecutive cycles, which was attributed to the formation of graphite carbon-coated Co NPs structure during the synthesis process. This simple fabrication strategy provides a novel approach for the modification of mesoporous molecular sieves with excellent catalytic activities.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317709","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}

The CQDs effectively absorb UV and visible light, aiding electron transfer to NiPc, which significantly boosts photocurrent generation and reduces the overpotential. Electrochemical tests, including cyclic voltammetry and chronoamperometry under UV and blue light, show that the NiPc/CQD hybrid system delivers a notable increase in photocurrent density and stability compared to bare NiPc electrodes. By a membrane-free Clark-type electrode, molecular oxygen generated during photoelectrochemical water oxidation was detected. This sustainable system underscores the potential of biomass-derived CQDs as efficient, low-cost nanomaterials for solar-driven water oxidation, advancing renewable energy technologies.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202401691","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the recalcitrant nature of lignin to degradation has been a major hurdle in the valorization of lignin. The depolymerization (catalytic and pyrolytic) of lignin results in the formation of lignin-derived bio-oil comprising low-molecular-weight phenolic compounds (monomers, dimers, and oligomers) with much higher oxygen content than that required for the fuels. The catalytic hydrodeoxygenation (HDO) of lignin-derived phenolic compounds is one of the alluring opportunities for converting biomass materials to chemicals and fuels. The current article systematically reviews the advancement in the production of cyclohexane-based compounds from five primary lignin-derived monomers, phenol (PHE), guaiacol (GUA), cerulignol (CER), eugenol (EUG), and vanillin (VAN) using supported ruthenium (Ru) catalysts. The carbon-based zeolites and TiO2-based materials with distinguished properties are explored as the support for Ru nanoparticles. Understanding the characteristics of metal and its supports, along with the catalytic mechanisms and structure-activity relationships is crucial in developing HDO catalysts to produce selective products from lignin-derived phenolic monomers for practical applications. This review particularly highlights the significance of the synergistic interactions between ruthenium and the support materials during HDO reactions.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 18","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202501116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supported catalytically active liquid metal solutions (SCALMS) based on Ga–Pt alloys offer high selectivity and coke resistance, yet their vast compositional and operational design space hampers efficient optimization. We compiled and FAIR-formatted 198 PDH experiments on Ga-Pt SCALMS, distilling 149 complete cases with 20 descriptors covering synthesis, support, metal loadings, reaction conditions, and four key performance indicators: low deactivation, high selectivity, conversion, and productivity. Exploratory statistics revealed strong Ga–Pt loading covariance, pretreatment-temperature effects on stability, and a distinctive high-conversion/high-selectivity but fast-deactivating regime for Ga2O3-Pt catalysts prepared reductively on CARiACT silica. Principal-component analysis captured 34% of variance in two dimensions, isolating clusters linked to support and pretreatment protocols. Feature-reduced datasets fed three machine-learning regressors; extreme gradient boosting achieved the best extrapolation for productivity (R2 = 0.58), Random forests best predicted deactivation (R2 = 0.43), while support vector regression yielded the most accurate conversion predictions (R2 = 0.68). SHAP analysis ranked pretreatment temperature, Ga/Pt ratio, and time-on-stream as dominant drivers of KPI variance, aligning with SCALMS mechanistic expectations. Validation on six new experiments confirmed model fidelity within ± 15% for conversion, productivity, and deactivation. The combined statistical-predictive workflow constitutes a catalyst-informatics framework that guides catalyst development based on experimental data and highlights the need for larger, standardized datasets to reach truly predictive design of liquid–metal catalysts.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500893","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the types of reactions catalyzed by class I aldolases are restricted and radical reactions have yet to be accomplished. Here, we demonstrate a proof-of-concept study in which a synergistic photoredox biocatalysis strategy can be applied to realize new catalytic functions of enamine-dependent aldolases. This new reactivity enables asymmetric alkylation of a prochiral radical under exclusive stereocontrol, a challenging task for amine catalysts. Both enantiomeric products were obtained in a stereoconvergent fashion from wild-type and engineered aldolases. This synergistic photoredox biocatalysis strategy has resulted in a new-to-nature enzymatic reaction and led to an asymmetric transformation that is not feasible for organocatalysis.

In this work, Ru supported on acid-treated sepiolite (Ru/ASep) is designed for the reductive amination of furfural (FUR) to furfurylamine (FUA) using H2 and NH3 as reductant and nitrogen source, respectively. Ru/ASep exhibited two times higher catalytic activity compared to its counterpart, that is, Ru supported on parent sepiolite (Ru/Sep), yielding 98.4% FUA. The NH3-temperature-programmed desorption (TPD) and NH3-diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy studies show that Ru/ASep exhibited an increase in total acidic sites with relatively more Lewis acidic sites than Ru/Sep, contributing to C═N bond activation and leading to the formation of FUA in high yield. The CO2-TPD results indicate that ASep possesses a large amount of basic sites, which contribute to a facile reduction of RuOx to Ru0 in Ru/ASep, as confirmed by H2-temperature programmed reduction (TPR) studies. H2-TPD studies indicate a higher amount of H2 activated over Ru/ASep, favoring the intermediate hydrogenation step to form FUA. Furthermore, the poisoning studies with KSCN indicated that Lewis acidic sites on the surface of Ru/ASep played a crucial role in the formation of FUA.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317735","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}
