Decomposition Reactions of Nitrogen Oxides in Direct Current Glow Discharges.
NTIS: PB 245 824 :19 pages
Studies were conducted by the Bureau of Mines to determine the positive ions and neutral species produced in glow discharges of gas streams containing 1.0 percent no in helium, 29 percent dry air in helium, and 1.06 percent no in n2. Mass spectographic measurements were conducted for gas pressures from 2.3 to 10.0 Torr and DC currents from 10 to 20 ma. Ion species observed included no+, n2+, o2+, n+, and o+ with lesser amounts of he+, he2+, and NO2+. Variations in various ionic and neutral species with discharge duration were interpreted to be consistent with an electrically induced dissociation of no to produce n2 and o2. No nitrogen oxides were observed to form in glow discharges of the helium-air mixture.
