摘要：
In this paper we investigated the particular behaviour of the nickel ion to serve as divalent cations for M-II/Fe-III and M-II/Al-III layered double hydroxides. To this end, we showed by careful TEM/EDX, PXRD and infrared analysis the possibility to accurately tune the composition of Ni-based layered double hydroxides in the range 0.09 <= M-III/(Ni-II + M-III) <= 0.33. The morphology of the crystals was strongly correlated to the net charge of the layer. Finally, we confirmed the trends of structural parameters observed in literature for other M-II/M-III LDHs synthesized in narrower ranges of composition. (C) 2010 Elsevier Masson SAS.
