Efficient adsorbents for removal heavy metals are extensively urgent in modern society. Metal-organic frameworks (MOFs) with abundant porosity and tunable structure make it potential to access the advantages of high permeability and adsorbability in water pollutant control. However, MOFs nanoparticles inconvenient to recycle in solution hinder its application in water pollutant treatment. Herein, we report an in-situ growth and large-scalable manufacturing method to fabricate ZIF-8 nanoparticles on electrospun polyacrylonitrile (PAN) nanofibers membrane (ZIF-8/PAN NF) by hot pressing. Consequently, the prepared ZIF-8/PAN NF possesses high loading, uniform dispersion and large-scalable area as well as good flexibility. The fabricated ZIF-8/PAN NF exhibits excellent performance with fast flux (12,000 L/(m²h)) and high filtration efficiency (96.5%) for Cu²⁺ in dynamic adsorption. Additionally, adsorption and electrochemistry are introduced simultaneously. The Cu²⁺ removal rate of ZIF-8/PAN NF reaches 34.1% in 4 min with combination of adsorption and electrochemistry. While it is 29.2% for Cu²⁺ elimination in adsorption. Given the outstanding performance and easy manufacture, this study might bring MOFs powder to eliminate water pollution into practical application.

在现代社会中，用于去除重金属的有效吸附剂已迫在眉睫。具有高孔隙率和可调结构的金属有机框架（MOF）使其有可能在控制水污染物中获得高渗透性和吸附性的优势。然而，MOFs纳米粒子在溶液中不方便回收，阻碍了其在水污染物处理中的应用。本文中，我们报道了通过热压在电纺聚丙烯腈（PAN）纳米纤维膜（ZIF-8 / PAN NF）上制备ZIF-8纳米粒子的原位生长和大规模制造方法。因此，制备的ZIF-8 / PAN NF具有高负载，均匀分散和大面积可缩放以及良好的柔韧性。制成的ZIF-8 / PAN NF表现出优异的性能，并具有快速通量（12,000 L /（m ²h））和动态吸附中Cu ^2+的高过滤效率（96.5％）。另外，吸附和电化学同时引入。吸附和电化学相结合，ZIF-8 / PAN NF的Cu ²⁺去除率在4 min内达到34.1％。Cu ²⁺的吸附去除率为29.2％。鉴于其优异的性能和易于制造的特点，本研究可能将MOFs粉末用于消除水污染，并将其投入实际应用。
