Synthesis of Carboxylic Acids Intercalated Mg-Al Layered Double Hydroxides by a Modified Reconstruction Method

Abstract:

A series of saturated and unsaturated fatty acids (i.e. sorbic acid, octanoic acid, lauric acid, stearic acid and oleic acid) were successfully intercalated into Mg-Al layered double hydroxides (LDHs) using a modified reconstruction method, as confirmed by X-ray diffraction (XRD), Fourier transformed infrared (FTIR) and thermal gravimetric analysis (TGA). The fatty acid intercalated LDHs thus prepared exhibit much better well-defined hexagonal platelet structure than samples prepared by the conventional reconstruction method.
