Engineering Faradaic Electrode Materials for High‐Efficiency Water Desalination

Small, Journal Year: 2024, Volume and Issue: 20(32)

Published: March 15, 2024

Abstract Water desalination technologies play a key role in addressing the global water scarcity crisis and ensuring sustainable supply of freshwater. In contrast to conventional capacitive deionization, which suffers from limitations such as low capacity, carbon anode oxidation, co‐ion expulsion effects materials, emerging faradaic electrochemical deionization (FDI) presents promising avenue for enhancing performance. These electrode materials employed charge‐transfer processes ion removal, achieving higher capacity energy‐efficient high salinity streams. The past decade has witnessed surge advancement considerable efforts have been made explore optimization strategies improving their This review summarizes recent progress on underlying mechanisms pursuit high‐efficiency desalination, including phase, doping vacancy engineering, nanocarbon incorporation, heterostructures construction, interlayer spacing morphology engineering. points each strategy design principle, modification method, structural analysis, mechanism are discussed detail. Finally, this work highlights remaining challenges present perspectives future research.

Enhanced Removal of Cu²⁺ and Pb²⁺ Ions from Wastewater via a Hybrid Capacitive Deionization Platform with MnO₂/N-Doped Mesoporous Carbon Nanocomposite Electrodes

Published: Feb. 21, 2025

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.
