Porous materials are widely studied for water purification and treatment as they can function as efficient adsorbents for harmful chemical wastes with their high specific surface areas. Among various types of porous materials, metal‐organic frameworks (MOFs) have emerged as promising adsorbents for organic pollutants although the general powder form of MOFs largely limits their recyclability in practical applications. Herein, highly crystalline MOF particles are incorporated into agarose (AG) to fabricate highly recyclable MOF aerogels. Along with greatly improved recyclability, these MOF aerogels also achieve eco‐friendliness and cost‐effectiveness because AG is highly abundant in nature and can be easily modified. Typically, MOF aerogels are synthesized by uniformly dispersing MOF particles into the AG solution. The resulting MOF aerogels show significantly improved efficiency for dye adsorption. It is believed that this fabrication method for the preparation of MOF aerogels is highly versatile and it can be extended to other types of MOFs for different applications including environmental remediation, energy storage and conversion, and sensing.

含MOF的气凝胶成形在实际水处理中的通用方法

多孔材料已被广泛用于水的净化和处理，因为它们可以用作具有高比表面积的有害化学废物的有效吸附剂。在各种类型的多孔材料中，金属有机骨架（MOF）已成为有前途的有机污染物吸附剂，尽管MOF的一般粉末形式在很大程度上限制了其可回收性。在此，将高度结晶的MOF颗粒掺入琼脂糖（AG）中以制造高度可回收的MOF气凝胶。除了大大提高了可回收性外，这些MOF气凝胶还具有生态友好性和成本效益，因为AG的性质非常丰富且易于修改。通常，通过将MOF颗粒均匀分散在AG溶液中来合成MOF气凝胶。所得的MOF气凝胶显示出显着改善的染料吸附效率。可以相信，这种用于制备MOF气凝胶的制造方法具有高度的通用性，并且可以扩展到其他类型的MOF，以用于不同的应用，包括环境修复，能量存储和转换以及传感。
