摘要

Catalyst comprises a carrier material (2) made of alpha - or gamma -aluminum oxide and a coating (3) applied on the carrier material. The coating contains rhodium as the active component. An independent claim is also included for an apparatus for the decomposition of nitrous oxide in a gas stream, comprising a gas carrying pipe having catalyst arranged in it.
