Abstract

A metal-organic-framework-based ion trap was designed via tailoring linker functionality as well as free -COOH density. The mixed-linker UiO-66-H₂/H₄ exhibits higher adsorption for Li⁺ ions than H₄-free UiO-66-H₂ because the H₄ linker provides an additional -COOH group in the local region.
