In this study, we developed an inverse design framework that integrates machine learning and a genetic algorithm (GA) for the intelligent design of high-performance ionic liquids. The framework uses an XGBoost model to predict CO₂ absorption capacity, employs SHAP analysis to elucidate structure-property relationships, and leverages the GA for molecular structure optimization aimed at maximizing CO₂ loading. Systematic evaluation of 12 MDEA-IL blends (867 experimental data points) shows that the comparison between the group contribution method and RDKit descriptors yields similar accuracy in predicting CO₂ absorption capacity, thereby validating the rationality of the selected molecular fragments. SHAP analysis identifies pressure as the most influential parameter and highlights the positive contribution of CH₂ group to CO₂ loading. Under simulated flue gas conditions, the framework successfully designs novel ionic liquids, with a candidate consisting of [Im₁₃]⁺ and [Ac]⁻ achieving optimal CO₂ loading (1.1048–1.1212 mol/mol) across all pressure regimes, outperforming existing benchmark systems.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"6 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146135502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sputtering power conditions of 100 W, 150 W, and 200 W were applied, obtaining, respectively, 0.22%, 0.40%, and 3.41% of Al-covering for the adsorbents named <em>Al@100 W</em>, <em>Al@150 W</em>, and <em>Al@200 W</em>. Kinetic analyses fitted to the pseudo-first-order model showed excellent agreement with the experimental data, with better predictive accuracy, particularly for DC. Adsorption equilibrium was achieved at 120 min for CZ and 60 min for DC. Equilibrium isotherms exhibited L2-type profile, suggesting strong adsorbate–adsorbent affinity. The Sips model best described the equilibrium data, evidencing a heterogeneous adsorption process promoted by aluminum deposition. Decreasing Sips (<span><span><math><mi is=\"true\">m</mi></math></span><script type=\"math/mml\"><math><mi is=\"true\">m</mi></math></script></span>) parameters with increasing sputtering power reflected enhanced surface heterogeneity and adsorption favorability. The maximum adsorption capacities reached were 260.7 mg g⁻¹ for CZ and 277.5 mg g⁻¹ for DC onto <em>Al@200 W</em>, representing an improvement of about 35% compared to raw biochar. Regeneration tests showed excellent reusability through the first five cycles; thereafter, coating deterioration greatly diminished the material's efficacy. Finally, magnetron sputtering proved to be an effective strategy, confirming that adsorption efficiency was governed by both aluminum loading and surface chemical modification, thereby enhancing adsorption capacity, affinity, and durability toward pharmaceutical contaminants.","PeriodicalId":427,"journal":{"name":"Separation and Purification Technology","volume":"30 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146135561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a p-n heterojunction catalyst composed of Co₃O₄ and Fe₂O₃ with strong interfacial coupling effect was rationally synthesized to overcome the intrinsic limitations, thereby achieving efficient photothermal mineralization of toluene. Under full-spectrum irradiation (350 mW/cm²), the Fe₂O₃/Co₃O₄ (0.15-FCO) p-n heterojunction achieved a toluene conversion rate of 99.72% and a CO₂ yield of 87.94%, outperforming individual oxides.

Besides, the appropriate band potentials of the p-n heterojunction facilitated charge carrier migration and activation of molecular oxygen. The results of in-situ DRIFTS further demonstrate that the incorporation of Fe₂O₃ promotes the oxidative conversion of intermediates on Co₃O₄ through interfacial charge transfer and sustaining active oxygen species generation.

Four commercial elements (TBW-HR, TMG(D), TM800M, and NRSP-UBT) were benchmarked at bench-scale using 4-in. modules under an equal-flux basis. Neutral-solute transport was parameterized by an apparent urea permeability, B_urea <!-- -->, derived from the observed urea rejection.

Herein, an Au/faceted Bi₂O₂CO₃@Mn₃O₄ core@shell heterostructure was engineered for enhanced NO oxidation and clothianidin (CLO) degradation. Specifically, the interleaved slit architecture of Bi₂O₂CO₃ with exposed {001} facets enhanced light scattering and surface energy, promoting visible light absorption and oxidation reactions. Notably, plasmonic Au nanoparticles synergized with Mn₃O₄ to induce dipole resonance due to symmetry of the electric field vector, amplifying the local electric field and broadening the spectral response. Meanwhile, Au mediated charge redistribution between Mn₃O₄ and faceted Bi₂O₂CO₃, generating a giant internal electric field (IEF) that accelerated charge separation. Consequently, the heterostructure achieved 73.2% NO removal with 93.5% NO₃⁻ selectivity and minimal NO₂ formation (28.6 ppb), as well as 95.6% CLO degradation under visible light, ultimately converting into non-toxic products, which exceeded reported benchmarks. The enhanced activity originated from Mn₃O₄/Au-induced dipole resonance–assisted <em>Z</em>-scheme charge transfer combined with IEF-driven carrier separation and prolonged lifetimes.

In this work, a novel sandwich-structured monolithic catalyst, denoted as ERI@Co_1.0Fe_0.6-MnO_x@Cor (where ERI stands for erionite), was successfully fabricated. This was achieved by sequentially constructing a CoFe-MnO_x intermediate catalytic layer via an impregnation-coprecipitation method and an outer zeolite ERI shell through a dip-coating process on the cordierite support. The optimized catalyst exhibits exceptional NO_x conversion (&gt;95%) within a broad temperature window of 150–350 °C, achieving complete conversion (100%) at 150 °C. More importantly, the sandwich structure endows the catalyst with superior resistance to H₂O and SO₂, maintaining over 90% NO_x conversion at 150–250 °C even in the presence of 5 vol% H₂O and/or 100 ppm SO₂. This performance is significantly superior to that of all previously reported counterparts. Characterization results revealed that the Co–Fe–Mn ternary synergy enhances redox properties via increased Mn⁴⁺ and chemisorbed oxygen concentrations, while the ERI zeolite shell as a protective barrier was identified as the key factor responsible for the enhanced medium-strength acid sites and exceptional poisoning resistance.

At the same time, their high specific surface area and porous structure provide abundant active sites. They also maintain stable mechanical properties under harsh conditions, synergistically boosting conversion efficiency and product selectivity. This review examines the use of carbon materials as catalytic supports for the thermal hydrogenation of CO₂ to C1 products. Initially, we elucidate the mechanism by which carbon-based support promotes the CO₂ hydrogenation reaction. Subsequently, the synthesis method of various carbon-based catalyst composites designed for the thermal hydrogenation of CO₂ was summarised. Furthermore, we provide a comprehensive comparison of the catalytic activity and selectivity of carbon-supported catalysts, offering insights into how different dimensions of carbon-based carriers influence the catalytic performance toward the production of methane, methanol, formic acid, and carbon monoxide.

Mechanism analysis revealed that kaolinite modulates the particle size of Fe_1-xS to effectively minimize the agglomeration, thereby facilitating the activation of PMS and enhancing both thermal and chemical stability. This significantly boosts the generation of reactive oxygen species (ROS), e.g., SO₄^⋅−, ^⋅OH, ¹O₂, and ^⋅O₂⁻ in the degradation system, thus exhibits an exceptional potential for natural water and wastewater treatment due to its broad resistance to environmental interference.
