The invention describes a highly efficient catalytic pollution control process for removing N₂O from gaseous mixtures. The process utilizes catalysts derived from anionic clay minerals, which after appropriate heat activation, provide superior N₂O decomposition activity. The catalytic process comprises contacting an N₂O-containing gaseous mixture with the decomposition catalyst under conditions sufficient to convert the N₂O into gaseous nitrogen and gaseous oxygen. The process catalysts are derived from anionic clay materials such as the hydrotalcites, sjogrenites and pyroaurites. |
