Achieving separation of lithium and magnesium with similar radii is crucial for the current extraction technology from salt lakes, which usually possess a high lithium-to-magnesium ratio. Herein, we proposed facile sequential interfacial polymerization (SIP) approach to construct electronanofiltration membranes (ENFMs) bilayer charged structure consisting positively surface negatively sublayer. The trimesoyl chloride (TMC) concentration was adjusted enhance -COOH content negative charge...
Advancing electrode materials with high adsorption capacity and fast rate is crucial for seawater desalination in capacitive deionization (CDI). Here, we propose a highly oriented, densified graphene (HODG) characterized by its ordered/short ion transport channels, abundant oxygen functional groups, packing density (1.374 g cm–3), large specific surface area (543.72 m2 g–1), facilitating exceptional diffusion ultrahigh volumetric capacity. HODG delivers capacitance of 308 F cm–3 at 1 A g–1,...
Conventional solarizing seawater suffers from inefficiency and space constraints. Interfacial solar vapor generation (ISVG) presents an energy-efficient alternative, yet the scalability, adaptability, durability of a evaporator for practical use are remaining concerns. Herein, hydrogen-bond-repairing featuring reconstructed large-width channels is proposed ongoing solarization in ISVG. The polyacrylamide/trehalose/graphene hydrogel (PTGH) exhibits excellent mechanical properties salt...
Inspired by the charge-governed protein channels located in cell membrane, a series of polyether ether ketone-based polymers with side chains containing ionically cross-linkable quaternary ammonium groups and acidic have been designed synthesized to prepare monovalent cation-selective membranes (MCEMs). Three (sulfonic acid, carboxylic phenolic hydroxyl) different acid dissociation constant (pKa) were selected form ionic cross-linking structure membranes. The induced nanophase separation...
