Mg-Al mixed oxides with molar ratio of Mg/Al = 1-3 were prepared by co-precipitation and characterized by using X-ray diffraction, scanning electron microscopy, BET surface area and pore volume measured by $N_2$ sorption analysis, and temperature programmed desorption of iso-propanol. As Al content in Mg-Al mixed oxide increased, the acidity and BET surface area proportionally increased. This increase of acidity directly influenced the catalytic activity of iso-propanol conversion and selectivity to propylene.
