To elucidate the network of reactions occurring in the experiment described before, the catalytic activities in the following reactions/settings were tested: dehydrogenation of 2-propanol or so called "2-propanol TPR" (5. For the dehydrogenation of 2-propanol/"2-propanol TPR" the temperature was raised to 600 °C starting from 50 °C at a rate of 5 °C•min -1 . For all the other reactions/settings the temperature was raised to 400 °C starting from 50 °C at rate of 3 °C•min -1 . In contrast to the experiments on the oxidative dehydrogenation of 2-propanol no second cycle was run. Ex-situ XRD measurements of the samples were carried out after all the experiments as described above.
