Electrified ceramic membranes (ECMs) achieve high water decontamination efficiency mainly through implementing in situ radical-mediated oxidation in membrane filtration, whereas ECMs leveraging non-radical pathways are rarely explored. Herein, we demonstrated a Janus ECM realizing ultra-efficient micropollutant (MP) removal via electro-activating peroxymonosulfate (PMS) in a fast, flow-through single-pass electro-filtration. The Janus ECM features two separate palladium (Pd) functionalized electrocatalytic reaction zones engineered on its two sides. We confirmed that the PMS/electro-filtration system induced non-radical pathways for MP degradation, including singlet oxygenation and mediating direct electron transfer (DET) from MP to PMS. Under the design of the ECM featuring dual electrocatalytic reaction zones in the ceramic membrane intrapores, the Janus ECM showed over one-fold increase in micropollutant removal rate as 94.5% and lower electric energy consumption as 1.78 Wh g⁻¹ MP in the PMS electro-activation process, as compared with the conventional ECM assembly implementing only half-cell reaction. This finding manifested the Janus ECM configuration advantage for maximizing the PMS electro-activation efficiency via singlet oxygenation intensification and direct usage of cathode for DET mediation. The Janus ECM boosted the PMS electro-activation and water decontamination efficiency by enhancing the convective mass transfer and the spatial confinement effect. Our work demonstrated a high-efficiency PMS electro-activation method based on electro-filtration and maximized the non-radical mediated PMS oxidation for MP removal, expanding the ECM filtration strategies for water decontamination.

带电陶瓷膜（ECM）主要通过原位实施实现高水净化效率膜过滤中自由基介导的氧化，而很少探索利用非自由基途径的 ECM。在此，我们展示了 Janus ECM 通过电激活过氧单硫酸盐 (PMS) 在快速、流通的单程电过滤中实现超高效微污染物 (MP) 去除。Janus ECM 在其两侧设计了两个独立的钯 (Pd) 功能化电催化反应区。我们证实 PMS/电过滤系统诱导了 MP 降解的非自由基途径，包括单线态氧化和介导从 MP 到 PMS 的直接电子转移 (DET)。在陶瓷膜孔内具有双电催化反应区的 ECM 设计下，Janus ECM 的微污染物去除率提高了一倍以上，达到 94。^-1 MP 在 PMS 电激活过程中，与仅实施半电池反应的传统 ECM 组件相比。这一发现表明了 Janus ECM 配置优势，可通过单线态氧化强化和直接使用阴极进行 DET 调节来最大化 PMS 电激活效率。Janus ECM 通过增强对流传质和空间限制效应来提高 PMS 电活化和水净化效率。我们的工作展示了一种基于电过滤的高效 PMS 电激活方法，并最大化了非自由基介导的 PMS 氧化以去除 MP，扩展了用于水净化的 ECM 过滤策略。
