Abstract Silver (Ag) is deemed a promising anode material for capacitive deionization (CDI) due to its high theoretical capacity and efficient selectivity Cl − . However, the strong volume change during conversion reaction significantly undermines cycling performance of Ag electrode. Additionally, achieving well‐dispersed in active matrix challenging, as electrodes prepared by conventional thermal reduction tend agglomerate. Herein, organic linker confinement strategy proposed, applying metal–organic framework (MOF) chemistry between nodes ligands construct Ag‐based MOF. The uniform dispersion at molecular level, confined matrix, efficiently enhances utilization sites, strengthens interfacial stability Ag. Consequently, Ag‐MOF CDI exhibits an excellent removal 121.52 mg g −1 20 mA 500 L NaCl solution, rate 60.54%. After 100 cycles, retention 96.93% achieved. Furthermore, capture mechanism elucidated through density functional theory (DFT) calculations, ex situ XRD, Raman XPS. This ingenious electrode design can offer valuable insights development high‐performance applications.

Integrating MnO2 with carbon is a reliable strategy to improve capacitive deionization (CDI) performance by leveraging the unique properties of both components (i.e., and carbon). However, influences preliminary functionalization (e.g., nitrogen doping, KOH activation) pairing cathodes anodes on CDI have yet be systematically explored. Herein, we prepared group MnO2-decorated mesoporous composites as dopant MK-NMCS, K-NMCS, NMCS, CS), evaluated desalination various cathode//anode pairs in hybrid (HCDI) for capturing Na+, Cu2+, Pb2+, respectively. Of all electrodes, MK-NMCS//K-NMCS pair demonstrates optimum based salt adsorption capacity (SAC) cycling stability, offering SAC 25.4 mg g-1 retention 102.4% after 50 consecutive charge-discharge cycles at 1.2 V 500 ppm NaCl solution. In addition, electrodes also show maximum ion (IAC) toward Cu2+ Pb2+ ions compared other pairs, attaining an IAC 37.0 30.0 per gram electrode materials 200 solutions, respectively (cf. 32.2 solution). Besides, these exhibit excellent stability when applied removing each heavy metal separately, retentions 90.0 98.5% ions, Mechanical analysis reveals that metals are likely sequestered via electrosorption carbon, intercalation MnO2, surface complexation external [MnO6] octahedral layers. Our results demonstrated great potential N-doped carbon//prefunctionalized particular, HCDI platforms. Such prefunctionalization strategies very promising screening high-performance composite wastewater remediation.
