ABSTRACT
Recent advancement of nanocatalysis has lead researchers to develop new techniques for synthesis of nanocatalysts. One such technique is the reverse microemulsion method, which is recently used for the synthesis of layered double hydroxides (LDHs). This chapter deals with the reverse microemulsion technique and coprecipitation technique for synthesizing nano LDH, their structural characterization and uses for photocatalytic removal of cationic and anionic dye pollutants from aqueous solutions. Synthetic methodology for a series of CoZn LDH nanosheets using sodium dodecyl sulfate (SDS), isooctane, and water will be discussed. We will also discuss the effect of water to SDS molar ratio in the synthesis mixture toward the formation of final nanostructure followed by discussion of synthesis of ZnFeLDH via coprecipitation method.
