To overcome these limitations, a novel acidic cross-linking strategy was developed using silicon-containing reactive dyes and the silane coupling agent (3-aminopropyltriethoxysilane, KH550). Under weak acidic conditions (pH = 5.0), a three-dimensional “dye-cross-linker-fabric” cross-linking network was successfully constructed through reactions between silanol groups and fabric hydroxyl groups, reactions between the amino groups of KH550 and the reactive groups of the dyes, and self-condensation of silanol groups, thereby fixing the dyes onto the fabrics. This method achieved high fixation rates of 91.3%–96.4%, with excellent wash and rubbing fastness. Furthermore, by selecting matching disperse dyes, one-bath one-step dyeing of polyester/cotton was realized. The thermosol process for disperse dyes did not hinder reactive dye fixation, and KH550 even enhanced disperse dye uptake. Total dye utilization exceeded 90%, with outstanding fastness and levelness. This approach shortens the dyeing process, reduces energy use and effluent load, offering an efficient and eco-friendly alternative for blended fabric dyeing.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"20 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, during optimization procedure, a large number of infeasible solutions are generated, hindering efficient exploration of feasible, high-performance regions of the search space. In this study, we propose a data-driven identification and adaptive directed correction strategy for handling infeasible solutions, and on this basis, develop an efficient multi-objective optimization framework (MO-DIDC) for complex distillation processes. By identifying infeasible solutions that closely resemble high-performance ones, the framework leverages them to accelerate convergence to optimal designs. A surrogate model is trained to distinguish high- and low-performance solutions and is then used to identify potentially high-performance candidates within the infeasible set. Through similarity analysis, the most influential variable is selected for correction to generate new promising solutions. This strategy reduces unnecessary exploration of infeasible regions and concentrates computational effort on feasible, high-quality solutions. Demonstrated on a side-stream double-column extractive distillation system and a four-column extractive distillation system, the proposed optimization framework outperforms a widely used genetic algorithm while substantially improving computational efficiency, achieving optimization time reductions of 35.3% and 20.8%, respectively.

The effective application of LOHCs requires dehydrogenation catalysts that strike an optimal balance between activity and stability. Herein, we report a precisely engineered CoO_<i>x</i>-modified Pt/Al₂O₃ catalytic system that exhibits outstanding performance in the dehydrogenation of perhydro-dibenzyltoluene (H18-DBT). Systematic investigations identify a critical CoO_<i>x</i> loading threshold at 1 wt%, at which the catalyst achieves a maximum dehydrogenation degree (DoD) of 93% and a H₂ production rate of <span>(20.98times 10^{3} text{mol}_{mathrm{H}_{2}}cdot text{mol}_{text{Pt}}^{-1}cdot mathrm{h}^{-1})</span> at 300 °C for dehydrogenation, outperforming all the catalysts reported in the literature. However, increasing the Co loading from 1 to 10 wt% results in a sharp decline in DoD from 93% to 7.2%. With the increasing CoO_<i>x</i> content, the cobalt species initially form amorphous CoO clusters, which subsequently transform into crystalline Co₃O₄. The amorphous CoO is found to be the key species responsible for enhanced dehydrogenation activity by increasing the electron density and reducing the particle size of Pt, thereby promoting dehydrogenation while suppressing the hydrogenation capability.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"20 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147642630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochar derived from agrowastes offers a sustainable alternative to conventional oxide supports owing to its low cost, high carbon content, tunable micro-mesoporosity, and ability to anchor metal nanoparticles. Herein, we design and evaluate date palm trunk biochar-immobilized mono and bimetallic Ni, Fe, and NiM (M = Fe or K) catalysts for CO₂ methanation.

Ni loading strongly influenced catalytic performance; the optimal catalyst (0.5 mmol Ni g⁻¹, BCNi-3.0) achieved 58% CO₂ conversion and 91% CH₄ selectivity at 400 °C and 1 bar. Increasing pressure to 30 bar enhanced performance to 76% CO₂ conversion and nearly 99% CH₄ selectivity, with stable operation over 20 h. Bimetallic NiFe catalysts formed NiFe₂O₄ and NiO phases and promoted CO formation via the reverse water gas shift reaction, while K promotion further favored CO production.

Notably, complete degradation (100%) of a 100 mg·L⁻¹ methylene blue solution was achieved at a residence time of merely 15.95 s and a plasma power of 17.3 W. Kinetic analysis revealed that degradation process follows a pseudo-first-order reaction model.

This review systematically examines recent advances in various V-based hydrogen storage alloy systems, including the hydrogen absorption/desorption mechanisms of vanadium-based alloys; performance modulation strategies and underlying mechanisms for ternary (V-Ti-Cr), quaternary (V-Ti-Cr-Zr), quinary and higher-order (V-Ti-Cr-Fe-Al) systems; the effects of crucial factors, including chemical composition and lattice parameters, on thermodynamic and kinetic properties during hydrogenation/dehydrogenation cycles; and comprehensive performance optimization strategies. Addressing current limitations including compositional complexity and high design costs, this review highlights the importance of employing machine learning models (e.g., random forest, deep neural networks) to establish composition-property relationships, combined with optimization algorithms for efficient screening of V-based compositions to guide performance modulation. Lastly, a comprehensive analysis is provided on the coupling interaction mechanisms of engineering factors in complex service environments and their significant effects on the long-term service performance of alloys.
