Summary: This study successfully developed a hollow Co-MOF-74 incorporated electrospun nanofiber membrane and a homemade filter device to remove polycyclic aromatic hydrocarbons (PAHs) from aqueous solutions. The prepared H-NFMs exhibited high removal efficiency and reusability, while the introduced H-Co-MOF-74 material had a large surface area and hollow structure that enhanced adsorption performance. By loading H-Co-MOF-74 in nanofiber membranes, the resulting H-NFMs showed high hydrophobicity, good mechanical and thermal stability, and could be easily recycled after adsorption.

Summary: This study demonstrates how defects can be introduced into porous ionic polymers using a defect-engineering strategy, allowing for control of pore size distribution, specific surface area, chemical stability, and gas adsorption performance. The presence of controllable vacancies and porosity in polymers was investigated using solid-state nuclear magnetic technique, showing improved ammonia adsorption performance compared to neutral and defect-free polymers. The strong interactions between gas molecules and the PIP-X are reversible, displaying outstanding recyclable ability without structure collapse, making defective anionic polymers a versatile type of ion-exchange material for gas uptake.

Summary: The growth of porous aromatic frameworks (PAFs) on the surface of polymer brushes is achieved for the first time. The confined environment provided by the polymer brushes leads to the formation of nanosized and homogeneous spherical PAFs. The size of PAFs can be controlled by adjusting reaction time, grafting density, and concentration of 4-bromobenzene.

Summary: Metal-organic frameworks (MOFs) have been widely studied for the removal of Cr(VI) from water. In this study, Fe-MOFs were successfully synthesized and immobilized in PAN nanofibers to create a composite electrospun nanofibrous membrane (PAN/MOFs ENFMs). The membrane showed rapid adsorption of Cr(VI) and maintained its adsorption capacity over a broad pH range. Immobilizing MOFs in ENFMs provides a new technological option for the removal of Cr(VI) from water.

Direct conversion of gold from e-waste to higher value materials is advantageous. In this study, a porous aromatic framework (PAF) called iPAF-7 was synthesized and demonstrated rapid extraction of gold from e-waste. An aerogel monolith incorporating iPAF-7 was also successfully fabricated, showing potential for continuous-flow catalysis.

Summary: This study presents a novel electrospun fiber adsorbents with high efficiency for capturing iodine species. The adsorbents can effectively remove iodine from both saturated iodine solution and iodide solution. The high iodine uptake capacity is attributed to the multiple active sites on the adsorbents, which exhibit high binding affinity towards iodine species through physical and chemical adsorption. Additionally, the adsorbents can be used as an adsorption column for dynamic iodine capture due to their macroscopic architecture.

Summary: The development of efficient adsorbents with anti-biofouling properties for uranium extraction from seawater is highly attractive. Inspired by the structures of phospholipid, the bio-inspired zwitterionic phosphate groups were created onto the electrospun nanofibers to manipulate the affinity with uranium and the anti-biofouling property. The constructed hyperbranched zwitterionic phosphate groups functionalized nanofiber adsorbents (ZP-PAN fibers) exhibited high distribution coefficient k(d) (7.38 x 10(6) mL/g) and large adsorption capacity (1294.0 mg g(-1)) in the uranium-spiked seawater, surpassing most of reported polymeric adsorbents.
