Here, we prepared Cu–Zn/γ-Al2O3 catalysts via the deposition–precipitation method to investigate the relationship among Cu–Zn content, contact, and interaction. We found that excessive Cu–Zn content leads to the aggregation of Cu and Zn species, while insufficient Cu–Zn content prevents effective separation of Cu by Zn. Additionally, the reduction and reaction processes of Cu–Zn/γ-Al2O3 were visualized. During the reduction process, ZnO (0 0 2) migrated to the catalyst surface, forming the ZnO (0 0 2)@Cu active site, where CO2 readily generates methanol via HCOO*. Therefore, enhanced Cu–Zn contact facilitates Zn migration, leading to the formation of active sites for methanol synthesis. The content-optimized 0.06Cu0.03Zn/Al2O3 exhibits 65.77% CO2 conversion and 88.32% methanol selectivity and displays better thermal stability than commercial CZA catalysts. We believe that our findings provide significant guidance and practical value for the industrialization of Cu–Zn catalysts in methanol synthesis.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"24 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622465","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}

Conventional recycling methods for textile waste are often limited by low efficiency, high cost, and low added-value outputs. Developing effective upcycling strategies for these textiles is crucial to minimizing their ecological footprint. Thus, this study reports a comprehensive strategy to upcycle cotton and cotton-polyester blend waste textiles into high value-added photonic materials. The process involves a two-step approach of acid hydrolysis and hydrothermal treatment. Acid hydrolysis efficiently extracts cellulose nanocrystals (CNCs) while preserving the intact structure of the polyester fibers for further reprocess. Hydrothermal treatment of the hydrolysis byproducts yields carbon quantum dots (CQDs) with tunable luminescent properties, maximizing the cellulosic utilization. CNCs and CQDs are then coassembled into large-scale biodegradable and recyclable photonic films with tunable structural color and circular polarized luminescence, promising applications in anticounterfeiting. A life cycle assessment highlights the minimal environmental impact of this process compared with traditional methods. This innovative approach offers a sustainable solution for textile waste management, contributing to the production of high-value-added materials.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"40 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622377","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}

The present work examined a new extraction system intended to improve the lithium ion extraction efficiency and the separation of lithium and magnesium while addressing problems associated with the use of FeCl3 as a coextracting agent. This system employed trioctyl phosphate as the extractant, NaBPh4 as the coextraction agent and 2-octanone as the diluent. The proportion of trioctyl phosphate, molar ratio of NaBPh4 to lithium ions and the organic/aqueous phase ratio were all optimized through experiments to give a single-stage Li+ extraction efficiency of 83.60%. In this process, the organic phase was washed with a solution of LiCl and NaCl to reduce the concentrations of Mg2+ and K+ to less than 1 mg/L. After three subsequent extractions of the organic phase with a Na2CO3 or NaHCO3 solution, the Li+ extraction efficiency was as high as 99%. During ten extraction cycles, the βLi+/Mg2+ value was maintained between 6000 and 7000, indicating good stability. Finally, the extraction mechanism was determined using infrared and nuclear magnetic resonance spectroscopy and these analyses confirmed the selective extraction of Li+. This new extraction system does not require acids or bases for regeneration of the organic phase, and the long-term operational stability of the organic phase is greatly improved.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"24 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622410","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}

The efficient degradation and utilization of TDI tar residue have become a tough challenge for TDI enterprises worldwide. Traditional landfill and incinerator processes do not properly use the organic resources in tar residue, and they also pose a danger of soil and air contamination. This study explores aminolysis using polyamines as a highly efficient alternative to TDI tar residue valorization. Aminolysis offers high degradation rates and TDA yields without requiring added catalysts or solvents, presenting a potentially atom-economical process. Using diethylenetriamine (DETA), a TDA yield of approximately 60% alongside the value-added coproduct 1-(2-aminoethyl)-2-imidazolidone (AEI) was achieved under optimized conditions. Density functional theory (DFT) calculations and experimental results support a three-step mechanism involving a sequential amine attack on urea linkages, followed by cyclization. This work demonstrates the potential of aminolysis as a cleaner and effective route for the chemical recycling of TDI tar residue.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"84 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622409","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}
