Abstract
In this work, the influence of the zinc content and synthesis methodology on the physicochemical properties of mixed oxide derivatives from the hydrotalcite precursor MgZnAl-HT were evaluated. Layered double hydroxides (LDH) were prepared by co-precipitation, ultrasound and urea hydrolysis methods followed by calcination at 500 °C. The materials were studied by such techniques as inductively coupled plasma, X-ray powder diffraction, Raman spectroscopy and 27Al solid-state NMR spectroscopy. The textural and morphological properties of mixed oxides were evaluated through the adsorption/desorption of N2 and scanning electron microscopy (SEM). Different textural and morphological properties were observed for the samples.
