Dual-scale molecular network lithium adsorbent

High-capacity selective Li capture

Encapsulating 12-crown-4 ether in ZIF-67 and embedding it in a lignosulfonate-based hydrogel creates hierarchical adsorption pathways, achieving both high adsorption capacity and high Li/Mg selectivity, along with antibacterial properties.
