Capacitive deionization (CDI) is a green and promising technology for seawater desalination, with its capacity industrial application being severely hindered by efficient electrode materials. Layered molybdenum disulfide (MoS2) has garnered significant attention CDI applications, while performance hampered weak surface hydrophilicity, high interfacial resistance, sluggish electron transport. Herein, we introduce an intercalation dual-engineering strategy covalently functionalizing the hydrophilic pyridine groups within 1T-MoS2 layer (Py-MoS2); electron-rich interface expanded interlayer spacing been achieved synergistically. A state-of-the-art desalination of 43.92 mg g-1 exceptional cycling stability have achieved, surpassing all reported existing MoS2-based electrodes. Comprehensive characterization theoretical modeling reveal that engineered enhance ion affinity via coordination, accelerate charge transfer, expand ion-accessible sites MoS2 through intercalation-induced structural modulation. These synergistic effects dramatically boost adsorption kinetics, mass transfer efficiency, salt uptake Py-MoS2 application. Our work presents to promote 2D materials, paving new insights next-generation high-performance development.

Quaternized Poly(ether sulfone) Coupled LiMn_1.9Cr_0.1O₄@Carbon Cloth for High-Performance Membrane Capacitive Li-Extraction

ACS Sustainable Chemistry & Engineering, Год журнала: 2025, Номер 13(1), С. 299 - 310

Membrane capacitive deionization (MCDI) is a promising Li-extraction technology from salty brine to meet the growing demand for lithium sources. In this work, Li+-selective quaternized poly(ether sulfone) coupled LiMn1.9Cr0.1O4@carbon cloth (LMC@CC/QPES) fabricated via rapid UV-curing method and used as flexible electrode in MCDI system. The results old West Taijinar confirm that optimal capacity can reach 28.57 mg·g–1 with retention rate of 82.36% after 200 cycles. This ascribed stereoscopic carbon current collector improving active loading charge transfer polymer binder buffer layer repressing initial manganese dissolution spinel LiMn1.9Cr0.1O4. Importantly, LMC@CC/QPES exhibits an enhanced Li+ selectivity (Li+/Mg2+ separation coefficient > 280) through ion sieving by lattice electrostatic repulsion membrane. Considering green preparation electrode, assembled system using QPES assisting LMC@CC provide considerable economic benefits recovery brine.
