Adsorption-responsive bionic photothermal ion pump for reversible seawater lithium extraction.

ABSTRACT: Lithium-ion sieve (LIS)-based adsorption technology offers a promising solution for seawater lithium extraction, as it overcomes the challenge posed by the high Na⁺/Li⁺ ratio. However, its broader application is hindered by the performance degradation and dissolution loss of LISs after granulation, as well as the low Li⁺ concentration in seawater. Herein, we propose an Albizia julibrissin-inspired adsorption-responsive photothermal ion pump (APIP) for enhanced and reversible Li⁺ extraction from seawater. The APIP integrates an interpenetrating network hydrogel with confined hydrogen manganese oxide (HMO) via an innovative in-situ crosslinking and ion-exchange strategy, ensuring the uniform distribution of HMO.
