| 1. A process for decomposing nitrogen oxides comprising the steps of:
a) providing a catalyst;
b) passing a gaseous nitrogen oxide over the catalyst;
c) exposing the catalyst to microwave energy; wherein the gaseous nitrogen oxide is broken down into nitrogen and oxygen molecules and wherein the nitrogen and oxygen molecules
react to form nitrogen dioxide.
