PREPARATION OF LAYERED DOUBLE HYDROXIDES

Abstract

Layered double hydroxides (LDHs) are class of materials with useful properties associated with their anion exchange abilities for a wide range of applications including bio and environmental problems. Synthetic methods have been examined to prepare LDHs with controlled structure, composition and particle morphology. Co-precipitation is a method used most widely while efforts have been made to conduct under controlled reactions conditions. In the present review article, synthetic methods for LDHs are overviewed with the emphasis on the authors' contribution.
