Several Co-Ni-Mg-Al-layered double hydroxides (LDH) have been synthesized by coprecipitation at constant pH = 9. All samples present well crystallized, layered structures, no excess phases were detected by X-ray diffraction, and the lattice a parameter followed the Vegard correlation. The cations th
The influence of the nature of the Zn, Al and Pt precursors, and of the temperature of precipitation and aging have been studied in connection with the preparation of Zn/Al and Pt/Zn/Al layered double hydroxides (LDH) by the sol-gel method. Whatever the precursors the XRD analysis shows that LDH is
