Hydrotalcite catalysts derived from NiAl and NiAlMg mixed oxides were successfully prepared by coprecipitation method at a constant pH of 11. The structural and textural properties of the catalysts were determined using physicochemical methods. The acid-base properties of the catalysts were investigated using isopropanol as a probe molecule, and their reactivity, selectivity, and lifetime were evaluated.
