Layered double hydroxide represents a class of materials for selective adsorption and catalysis. In the present work, anionic p-toluenesulfonic acid (PTSA) was successfully incorporated into interlayer domain Mg-Al layered (LDH), synthesized by co-precipitation route. Materials were characterized X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman magic angle nuclear ...
