LAYERED DOUBLE HYDROXIDES AS FUNCTIONAL MATERIALS AND THEIR TECHNOLOGICAL APPLICATIONS

Abstract

Layered double hydroxides (LDHs) have fascinated materials chemists due to their wide variety of applications in
various fields. The unique property of layered double hydroxides is their interlayer spacing that entertain the intercalation and
deintercalation variety of anionic species. Organic pharmaceutical drugs have been intercalated into the interlayer galleries of LDHs
and, consequently, novel nano drugs or smart drugs have revolutionized the medical field. LDHs, as green nanoreservoirs with
sustained drug release and cell targeting properties hold great promise of improving health and prolonging life. LDHs are employed
for the sorption of heavy and toxic metal ions, CO2 sequestration, electrode materials, materials of supercapacitors, polymer additives,
photocatalysts, heterogeneous catalysts etc., This chapter focuses on the general discussion of the synthesis, characterization and
applications of LDHs in various fields of research concern
