    • The UV-VIS spectra shown in figure l have been deconvoluted. As a result, the spectrum of a sample with vanadium loading of 7.2 wt% can be described by three bands with absorption maxima at 250, 292 and 362 nm, respectively, A more detailed description is given elsewhere [19].

    • Vanadia was deposited at the colder parts of the reactor during catalytic runs at lower temperatures. This is probably due to methanol-mediated volatilization of surface vanadium oxide. A similar behavior has been reported previously [11].

    • Spectra b (c)and d (e)were obtained after methanol oxidation within 200-240°C (400-460°C)for ∼14 h (∼10 h). Starting at 200°C (400°C), the temperature was kept constant for 200 min and subsequently increased by 30°C (30°C). It was kept constant for 200 min and then increased by 10°C (30°C). After the final temperature had been reached, it was kept constant for the residual duration of the experiment.
