Organic pollutants, with their increasing concentrations in the ambient air, are posing a severe threat to human health. Metal-organic frameworks (MOFs), due to their active functionalities and porous nature, have emerged as potential materials for the capture of organic pollutants and cleaning of the environment/air. In this work, the functionalization of cotton fabric is reported by the in-situ growth of zeolitic imidazolate framework (ZIF-8 and ZIF-67) MOFs on carboxymethylated cotton (CM Cotton) by employing a rapid and eco-friendly approach. The physicochemical characterization of the MOF functionalized fabrics (ZIF-8@CM Cotton and ZIF-67@CM Cotton) revealed uniform and wash durable attachment of porous ZIF nanocrystals on the surface of the fabric. These ZIF functionalized fabrics possessed high surface area and have been observed to adsorb significantly high concentrations of organic pollutants such as aniline, benzene, and styrene from ambient air. Interestingly these fabrics could be regenerated and reused repeatedly without any deterioration in their adsorption capacity. The negative and low binding energies calculated by DFT confirmed the physisorption of the aromatic pollutants on the surface of MOF functionalized fabrics. Such fabrics have a huge potential as protective textiles, anti-odor clothing, air purification filters, and related products.

随着有机污染物在周围空气中浓度的升高，对人类健康构成了严重威胁。金属有机框架（MOFs）由于其活性功能和多孔性质，已经成为捕获有机污染物和清洁环境/空气的潜在材料。在这项工作中，通过采用快速和生态友好的方法在羧甲基化棉（CM棉）上通过沸石咪唑酸酯骨架（ZIF-8和ZIF-67）MOF的原位生长来报道棉织物的功能化。MOF功能化织物（ZIF-8 @ CM棉和ZIF-67 @ CM棉）的理化特性表明，多孔ZIF纳米晶体均匀且耐洗地附着在织物表面。这些ZIF官能化的织物具有较高的表面积，并已观察到可从周围空气中吸附高浓度的有机污染物，例如苯胺，苯和苯乙烯。有趣的是，这些织物可以再生和重复使用，而不会降低其吸附能力。通过DFT计算得出的负和低结合能证实了MOF功能化织物表面上芳族污染物的物理吸附。这样的织物具有巨大的潜力，如防护纺织品，防臭衣服，空气净化过滤器和相关产品。通过DFT计算得出的负结合能和低结合能证实了MOF功能化织物表面上芳族污染物的物理吸附。这样的织物具有巨大的潜力，如防护纺织品，防臭衣服，空气净化过滤器和相关产品。通过DFT计算得出的负和低结合能证实了MOF功能化织物表面上芳族污染物的物理吸附。这样的织物具有巨大的潜力，如防护纺织品，防臭衣服，空气净化过滤器和相关产品。
