NO Synthesis Provided in Non-Thermal Plasma by Charged Particles

Mechanisms of NO Synthesis Provided in Non-Thermal Plasma by Charged Particles 

Dissociative recombination makes a contribution to the formation of N atoms, and NO synthesis  

The rate coefficient of the recombination (6-6) is kf 10 cm /s at electron temperature Te = 1 eV. After formation of atomic nitrogen, NO synthesis takes place in the exothermic reaction (6-3). Nj ions in non-thermal plasmas at elevated pressures have a tendency to form complex ions Nj N2 (or N4 see Fridman Keimedy, 2004), which decreases the yield of N atoms in the recombination. 

A significant contribution to NO synthesis in non-thermal air plasma can be provided by ion-molecular reactions, especially those involving positive atomic oxygen ions  

This reaction proceeds fast without any energy barrier but requires the formation of an expensive ion, 0+. An additional NO molecule can be produced in this case through exothermic reaction (6-3). NO synthesis can be also provided by ion-molecular reactions of molecular ions
