Facile synthesis of Zn-Al layered double hydroxide from aqueous suspension of zinc oxide and aluminum hydroxide

Abstract

Zn-Al layered double hydroxide containing benzenesulfonate was successfully synthesized by the hydrothermal reactions of aqueous suspension of zinc oxide and aluminum hydroxide in the presence of benzene sulfonic acid. The products were characterized by the sharp X-ray diffraction profile and platy particle morphology. The present very simple (hydrothermal reaction of the aqueous mixture) synthesis is applicable to a series of layered double hydroxides with different compositions and structures.
