文章亮点介绍：MIL-88A是一种金属有机框架（MOF）材料，以其优异的性能在高级氧化过程中（AOPs）而闻名。然而，由于其粉末状性质，MIL-88 A可能会在流动溶液中的催化降解过程中发生损失，使连续降解去除具有挑战性。在这里，我们报道了通过MIL-88与PVA海绵原位集成合成了MIL-88/PVA海绵复合材料。该复合海绵在硫酸根高级氧化过程（SR-AOPs）条件下表现出优异的四环素抗生素去除效率，在2分钟内达到99%以上的降解率。此外，通过固定床柱实验，1 kg的MIL-88 / PVA可以在24小时内处理2160升废水，表明其具有广阔的应用前景。值得注意的是，这种材料可以根据需要定制成任何所需的块状形状。这项工作为MOF基块状催化剂在SR-AOPs处理抗生素污染中的应用提供了非常有前途的解决方案。
MIL-88A is a metal-organic framework (MOF) material known for its excellent performance in advanced oxidation processes (AOPs). However, due to its powdery nature, MIL-88A may undergo loss during catalytic degradation in flowing solutions, making continuous degradation removal challenging. Herein, we report the synthesis of MIL-88A/PVA sponge composite material by the in-situ integration of MIL-88A with PVA sponge. The composite sponge exhibits excellent removal efficiency of tetracycline antibiotics under the conditions of sulfate radical-advanced oxidation processes (SR-AOPs), achieving a degradation rate exceeding 99% within 2 min. Additionally, through fixed-bed column experiments, 1 kg of MIL-88A/PVA can treat 2160 L of wastewater within 24 h, indicating promising industrial applicability. It's worth noting that this material can be customized into any desired block shape as needed. This work offers a highly promising solution for the application of MOF-based bulk-type catalysts in the treatment of antibiotic pollution using SR-AOPs.
