Evolution of protonic conduction in [Zn–Al–Cl] Lamellar Double Hydroxide phases with temperature and trivalent metal content

The conduction properties of a series of [Zn–Al–Cl] Lamellar Double Hydroxides (LDHs) with different amounts of trivalent metal are studied by impedance spectroscopy. The structural evolution of these samples is characterized by Rietveld analysis on powder X-ray diffraction diagrams. The conduction properties appear clearly related to the structural evolution of the interlayer domains.
