From: Design and synthesis of highly active MoVTeNb-oxides for ethane oxidative dehydrogenation

Arrhenius plot for ethene formation over M1 catalysts. The rate of a MoVTeNbOx catalyst prepared by the new synthesis method (low temp, MoV0.30Te0.05Nb0.05Ox) is compared with the rate over M1 prepared by standard method as in ref. 19 (high temp, MoV0.30Te0.06Nb0.08Ox). Rates normalized per mass of catalyst (a) and surface of M1 (b). T = 330–420 °C, p = 1 bar(a), WHSV = 6.8 h−1 (high temp sample), 14.5 h−1 (low temp sample)
