Abstract

Due to their high surface area, electronic properties, energy storage performance and catalytic activity, two-dimensional (2D) nanostructures have attracted significant interest and great attention in developing science. Layered double hydroxides (LDHs) belong to 2D nanostructures and have a high surface area, very important physicochemical properties, and biological activity. However, there has always been great interest in their doping to enhance and improve these unique properties, especially photocatalytic activity. In this work, ZnAl-based LDHs were synthesized and their doping with active- (Ca, Sr), transition- (Co, Cu, Cd, Ni, Pb, Fe), noble- (Ag) and rare earth- (La) metals were carried out by impregnation method. The removal of cationic and anionic dyes from aqueous solutions by adsorption and photodegradation on as-synthesized and doped ZnAl-LDH/PVA nanocomposite was also studied. The obtained results were correlated with the structure and physicochemical properties of the nanocomposites.
