Abstract:Layered double hydroxides (LDH) pillaring with organic anions CoAl-LDH are directly synthesized by a homogeneous precipitation method using the urea as a precipitiant,and the LDH products have been characterized through XRD,FT-IR,TGA and TEM.The results of all investigations show that urea homogeneous precipitation is a quick and simple method to obtain LDH pillaring with organic anions and CoAl-LDH,and can avoid the influence of anions in reactants.
Keywords:layered double hydroxides  synthesis  urea  organic anion  homogeneous precipition
