Abstract Adsorption is a classical physicochemical process, widely used in heterogeneous catalysis, chemical engineering, and environmental science. Regenerating the exhausted adsorbents or reversible desorption vital to achieving sustainable adsorption techniques, while common chemical/thermal regeneration energy‐intensive environmentally unfriendly. Given that adsorbents’ surface properties like charge electronic structures, significantly affect capacity kinetics, which offers opportunities for green by tailoring chemical/electronic features. Since certain adsorbate possesses specific energy on adsorbents, an electro‐desorption idea therefore proposed electrically control (sequential) release of aqueous substances regulating interfacial interaction above corresponding threshold potential. Herein, as proof‐of‐concept design, sub‐millimeter‐sized carbon nanotube‐reinforced conductive resin composite adsorbent with high conductivity mechanical strength developed, demonstrates efficiency toward benzoic acid (94.1%; 3 V negative bias) well‐controlled kinetics polarization. Using terephthalic model organic mixtures, exhibits efficient bias‐dependent sequential capability separating mixtures. This work provides promising solution desorption/regeneration pioneering electrically‐driven strategy mixture separation.

The strategic spatial positioning of ion affinity sites within biological channels and their cooperative binding with the targeted ions are pivotal for enhancing recognition ensuring exceptional selectivity in high ionic competition scenarios. However, application these principles to artificial remains largely unexplored. Herein, we present a series covalent organic framework (COF) membranes, engineered oxygen functional groups aligned along rims oriented COF pore varying sizes achieve precise arrangement sites. A notable membrane, featuring subnanometer pores decorated alternately carbonyl amide groups, demonstrated outstanding selectivity, achieving Li/Mg ratio 513 under equal mole electrodialysis conditions. Impressively, as Mg/Li source solution increased 16.6, rose 833, significantly exceeding reductions typically seen conventional selective nanofiltration methods. Both simulation experimental analyses indicate that this stems from between Li+ confined nanochannels, facilitating preferential transport ions.
