The effect of interlayer anion on the reactivity of Mg-Al layered double hydroxides: Improving and extending the customization capacity of anionic clays

► LDHs interfacial properties and reactivity depend on the interlayer anion. ► Chloride produces positive, hydrophilic particles with anion-exchange properties. ► DDS generate negative, hydrophobic particles with cation exchange capacities. ► These changes can be produced without changing the particles bulk composition. ► The surface properties tailoring extend and improve LDHs applications.
