The Supramolecular Structure of DDP Pillared Mg-Al-LDHs Compound
Layered double hydroxides (LDHs)/ Lauryl alcohol phosphoric acid ester(DDP) pillared compounds were synthesized by three different methods of co-precipitation, ion-exchange and calcined-rehydration respectively. The supramolecular structures of pillared compounds were characterized by power X-ray diffraction and Fourier transformation infrared spectra. The results indicated that DDP could intercalate into the interlayer of LDHs by three methods, but the supramolecular structure of pillared compounds had significant difference.
