The conjugation of metal-organic frameworks (MOFs) with other materials is an excellent strategy for the production of advanced materials having desired properties and so appropriate applicability. In particular, the integration of MOFs with a flexible paper is expected to form valuable materials in separation technology. Here we report a simple method for the generation of MOF papers through the compact and uniform growth of MOF nanoparticles on the cellulose surface of a carboxymethylated filter paper. The resulting MOF papers show a selective capture ability for negatively charged organic dyes and they can be used for dye separation through simple filtration of a dye solution on the MOF papers. In addition, MOF papers can be reused after a simple washing process without losing their effective dye capture ability.
金属-有机骨架（MOFs）与其他材料的结合是生产具有所需性质和适当适用性的先进材料的绝佳策略。特别是，将 MOFs 与柔性纸张集成有望在分离技术中形成有价值的材料。在这里，我们报告了一种通过在羧甲基化滤纸纤维素表面上紧凑且均匀地生长 MOF 纳米粒子来生成 MOF 纸的简单方法。所得的 MOF 纸对带负电荷的有机染料具有选择性捕获能力，并且可以通过在 MOF 纸上简单过滤染料溶液来进行染料分离。此外，MOF 纸在经过简单的清洗过程后可以重复使用，而不会失去其有效捕获染料的能力。
