Abstract
Described herein is a one-pot method for selective N2O and NO synthesis. A catalytic metal surface facilitates the oxidation of plasma-activated nitrogen species to produce nitrogen oxides (NO and N2O). The metal surface oxygen adsorption strength is critical in directing product selectivity to different nitrogen oxide (NxOy) products. Temperature regimes are important in directing product selectivity using Pt catalyst.
Claims21
A method for synthesizing nitrogen oxides (NxOy), the method comprising:
- introducing a first gaseous stream comprising nitrogen gas into a plasma reactor, energizing the plasma reactor, and generating a nitrogen plasma;
- contacting the nitrogen plasma with a noble metal catalyst and generating a plasma-activated nitrogen;
- introducing a second gaseous stream comprising oxygen gas into the plasma reactor, and oxidizing the plasma-activated nitrogen;
- and
- collecting a third gaseous stream comprising NxOy.
