Abstract
Layered double hydroxide (LDH) has positive charge between the layers and is known as anion exchangeable clay being able to intercalate various organic and inorganica nions. In this study, organic-inorganic layered nanohybrids were prepared by intercalation of organic carboxylate anions into Zn/Al LDH in an aqueous solution. Four intercalation compounds were prepared by the reactions of succinate, terephthalate, 4-pyridinecarboxylate, and p-hydroxybenzoate anions with Zn/Al LDH in aqueous solution. Interlayer spacing of these four intercalation compounds decreased by the thermal treatment at 363 K, and recovered by the treatment in water, reversibly.
