Simultaneously exposure of adsorption sites and shortening the transmission paths of target adsorbate are crucial for developing advanced adsorbents. In this work, an in-situ phase inversion-hydrothermal (PIH) method is reported to achieve the anchoring of nanosized metal organic frameworks (MOFs) at the interface of porous polymeric beads. Especially, ligand of MIL-101 was loaded in polyethersulfone (PES) beads via phase inversion process. Followed by hydrothermal process, nanosized MIL-101 was prepared in confined space and immobilized on the interface of PES Beads. The resultant MIL-101@PES Beads could provide shorter transmission paths and more exposed active sites, which avoid the blockage of pore structure in traditional embedded method. Removal of typical volatile organic compounds (VOCs), i.e., benzene-containing oil-and-gas, was chosen to present the adsorption performance of MIL-101@PES Beads. From the dynamic adsorption results, excellent removal ability and reusability were observed on the adsorbents. Beads-3 obtained under moderate feeding ratio presented superior adsorption capacity (245.56 mg/g for benzene and 228.82 mg/g for n-hexane) in mono-component adsorption with 2.52 times transport kinetics (intraparticle mass transfer coefficient of 2.09 s⁻¹) compared with embedded samples. These results demonstrated that MIL-101@PES Beads with shaped morphology and internal nanosized MOFs could serve as adsorbents in removing oil-and-gas. This work provides a novel protocol for the facile synthesis of shaped nanosized MOFs with enhanced performance for VOCs removal.

同时暴露吸附位点并缩短目标吸附物的传输路径对于开发先进的吸附剂至关重要。在这项工作中，报道了一种原位相转化-水热（PIH）方法，以实现纳米级金属有机骨架（MOF）在多孔聚合物珠粒界面的锚定。特别是 MIL-101 的配体通过相转化过程负载到聚醚砜 (PES) 珠粒中。随后通过水热工艺，在密闭空间中制备纳米级 MIL-101，并固定在 PES Beads 的界面上。由此产生的 MIL-101@PES Beads 可以提供更短的传输路径和更多暴露的活性位点，避免了传统嵌入方法中孔结构的阻塞。去除典型的挥发性有机化合物（VOCs），即含苯油气，选择展示 MIL-101@PES Beads 的吸附性能。从动态吸附结果来看，吸附剂具有优异的去除能力和可重复使用性。在中等进料比下获得的 Beads-3 在单组分吸附中表现出优异的吸附容量（苯为 245.56 mg/g，正己烷为 228.82 mg/g），传输动力学为 2.52 倍（颗粒内传质系数为 2.09 s）^-1 ) 与嵌入样本进行比较。这些结果表明，具有形状形态和内部纳米尺寸 MOF 的 MIL-101@PES 微珠可以用作去除油气的吸附剂。这项工作为轻松合成具有增强的 VOCs 去除性能的成形纳米 MOFs 提供了一种新的协议。
