AbstractThe pathways of ethane oxidative dehydrogenation and total combustion have been elucidated for M1 phase type Mo–V oxide catalysts with different metal composition. The ethane oxidation mechanism is not affected by the presence of Te or Nb. Conversely, the selectivity is strongly affected by stoichiometry of M1 catalysts. This is attributed to the facile oxidation of ethene to COx upon formation of unselective VOx species in the absence of Te and Nb.
