Coated: Surface analytical studies (including low-energy ion scattering (LEIS)) show that the outer surface of bulk, stoichiometric mixed vanadates and molybdates can be strongly enriched with VOx or MoOx species. Such surface reconstruction even in the calcined initial state has implications for the discussion of catalytic and other materials properties.
