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 VO x or MoO x species. Such surface reconstruction even in the calcined initial state has implications for the discussion of catalytic and other materials properties.
