Membrane catalysis is a frontier technology for effectively removing organic containments, and burgeoning membranes assembled from two-dimensional (2D) materials have significantly flourished in peroxymonosulfate (PMS)-based catalytic membrane processes. Here, a bottom-up strategy based on restricting CoFe Prussian blue analog (PBA) crystal growth in one direction is used to fabricate large-scale 2D blade-shaped PBA sheets, whose radial size and thickness can be adjusted by the precursor ion ratio (Co^II/Fe^II). The stripe CoFe PBA sheets can directly serve as building blocks and are simply assembled into a free-standing 2D membrane by interweaving assembly. The assembled CoFe PBA catalytic membrane possesses excellent wetting properties, guaranteeing an unimpeded mass transfer process, which leads to a superior instantaneous catalytic performance for the antibiotic norfloxacin during the continuous and flow-through membrane catalytic process. SO₄^•− and ¹O₂ are demonstrated to be the main active species, which synergistically contribute to the PMS-driven organic degradation.

膜催化是有效去除有机污染物的前沿技术，由二维 (2D) 材料组装而成的新兴膜在基于过氧单硫酸盐 (PMS) 的催化膜工艺中得到了极大的发展。在这里，基于限制 CoFe 普鲁士蓝模拟 (PBA) 晶体在一个方向上生长的自下而上策略被用于制造大型二维叶片状 PBA 片材，其径向尺寸和厚度可以通过前体离子比率进行调整（ CoⅡ / ^{FeⅡ _}). 条状 CoFe PBA 片材可以直接用作构建块，并通过交织组装简单地组装成独立的二维膜。组装的CoFe PBA催化膜具有优异的润湿性能，保证传质过程畅通无阻，从而在连续和流通膜催化过程中对抗生素诺氟沙星具有优异的瞬时催化性能。SO ₄ ^•−和¹ O ₂被证明是主要的活性物质，它们协同促进 PMS 驱动的有机降解。
