Herstellungsverfahren eines unterstützten Mischoxidkatalysators durch physikalische oder chemikalische Dampfphasenabscheidung

摘要

A supported catalyst comprising a mixed metal oxide is useful for the vapor phase oxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated carboxylic acid and for the vapor phase ammoxidation of an alkane or a mixture of an alkane and an alkene to an unsaturated nitrile. The mixed oxide catalyst is prepared by depositing a plurality of films of different elements using physical or chemical vapor deposition.
