However, the high cost and mass transfer limitations associated with traditional titanium silicalite-1 (TS-1) catalysts significantly hinder their industrial scalability. In this study, a novel chelating-agent-protected technique, combined with a tetrapropylammonium hydroxide (TPAOH) hydrothermal treatment strategy, was developed to achieve the uniform incorporation of nickel ions into the TS-1 framework. This dual approach effectively redistributed the charge density, modulated the surface acidity, and introduced hierarchical structures, thereby addressing the intrinsic diffusion and catalytic limitations of conventional microporous TS-1. Unlike conventional nickel modification methods, the chelating-agent-protected strategy successfully prevented nickel ion reduction or the formation of nickel oxide particles, ensuring highly dispersed and framework-integrated nickel species. The incorporation of nickel further enhanced the synergistic interaction with titanium, significantly reducing the binding energy of tetrahedral framework titanium (Ti<sup>4+</sup>) and enhancing the electrophilicity of active catalytic sites.

The results suggest that CuBTC demonstrates superior adsorption capabilities for all tested VOCs, due to its larger surface area and higher crystallinity. However, FeBTC has a broader pore sizes, allowing faster VOC mass transfer rates and accommodating larger molecules, albeit with slightly lower adsorption capacities. Notably, VOCs with polar and aromatic properties, such as 2-methylpyridine, exhibited higher adsorption levels due to increased π-π interactions within the frameworks. However, regeneration of 2-methylpyridine was challenging due to chemisorption, forming strong, irreversible metal–nitrogen coordination bonds. Toluene and 2-methyl-2-bustanol showed similar adsorption capacities and could be effectively regenerated, indicating physisorption mechanisms involving π–π interactions and polar interactions, respectively. N-hexane exhibited the lowest adsorption capacities, relying on weaker van der Waals forces. These results highlight the promising potential of CuBTC and FeBTC in mitigating air pollution.

This review explores the properties, applications, and limitations of MOFs in agriculture, emphasizing their role in advancing sustainable farming practices and highlighting perspectives for their integration into precision agriculture.</div></div>","PeriodicalId":392,"journal":{"name":"Microporous and Mesoporous Materials","volume":"391 ","pages":"Article 113609"},"PeriodicalIF":4.8,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
