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.

Synthesis of a MoVNbTe shell catalyst for oxidative dehydrogenation of ethane to ethylene

A simple, scalable, inexpensive, and reproducible method of selectively preparing the M1 phase of a MoVNbTe mixed oxide in a hydrothermal synthesis using tellurium dioxide is disclosed which can utilize inexpensive metal oxides as starting compounds.

Method for producing mixed oxide materials containing molybdenum

The present invention relates to a process for producing a composite material and also the composite material itself. The composite material contains a bismuth-molybdenum-nickel mixed oxide or a bismuth-molybdenum-cobalt mixed oxide and a specific SiO2 as pore former. The present invention also relates to the use of the composite material according to the invention for producing a washcoat suspension and also a process for producing a coated catalyst using the composite material according to the invention. Furthermore, the present invention also relates to a coated catalyst which has a catalytically active shell comprising the composite material according to the invention on a support body. The coated catalyst according to the invention is used for preparing [alpha],[beta]-unsaturated aldehydes from olefins.
