The catalytic activity of the materials in oxidative dehydrogenation of 2-propanol was tested at 2-propanol:O2 ratios of 2:1 and 1:1 at concentrations of 3.8 vol% 2-propanol and 3.8 vol% and 1.9 vol% O2, respectively with Ar as carrier gas in a total flow of 50 ml•min -1 . Starting from 50 °C, the reactor was heated to 400 °C at a heating rate of 2 °C•min -1 , kept at 400 °C for 30 min and cooled down to 50 °C at a rate of 2°C•min -1 again. Afterwards, a second cycle was carried out.
