Abstract

A novel coated catalyst having an outer shell which is composed of a catalyst material having high surface area and contains molybdenum, vanadium, tellurium and niobium, and the use of this catalyst for the oxidative dehydrogenation of ethane to ethene or the oxidation of propane to acrylic acid and also a process for producing the catalyst is disclosed.
