Catalyst, production method therefor and use thereof for decomposing N2O

摘要

The invention describes catalysts for decomposing NO into nitrogen and oxygen in the gas phase and with a porous carrier made of polycrystalline or glass-like inorganic material, a ceroxide functional layer which is applied thereto and a layer of oxidic material which contains cobalt and is applied thereto. The catalysts can be used, in particular, in nitric acid systems as secondary or tertiary catalysts.
