Macroporous cation exchange resin beads were subjected to hydrothermal treatment in a ZIF-8 yielding solution, resulting in resin beads–MOF composite. The resin beads were employed as a shaping template, providing carrier and support for the growth of MOF crystals. The conditions of synthesis were optimized so as to obtain maximum MOF loading. The final composites and their intermediates were characterized with complementary physicochemical methods, including XRD, SEM, thermal analysis (TG) and nitrogen sorption. The obtained composites were employed for water decontamination by targeting a dye (methyl blue) and a medical (antibiotic) contaminant. The composite adsorbent showed excellent recyclable removal ability, and exceeded the performance of its building components, i.e., the cation exchange beads and pure ZIF-8 material.

MOF-阳离子交换树脂复合材料及其在水净化中的用途†

将大孔阳离子交换树脂珠粒在ZIF-8生成溶液中进行水热处理，得到树脂珠粒-MOF复合材料。树脂珠粒用作成形模板，为MOF晶体的生长提供载体和支撑。优化了合成条件，以获得最大的MOF负载量。最终的复合材料及其中间体通过互补的物理化学方法进行表征，包括XRD，SEM，热分析（TG）和氮吸附。通过靶向染料（甲基蓝）和医学（抗生素）污染物，将获得的复合材料用于水净化。该复合吸附剂显示出极好的可回收利用的去除能力，并超过了其建筑组件的性能，即，阳离子交换珠和纯ZIF-8材料。
