Experimental study of surface contributions to molecule formation in a recombining N2/O2plasma

Abstract: Abstract. A low pressure recombining Ar plasma to which mixtures of N 2 and O 2 were added has been studied to explore the relevance of surface related processes for the total chemistry. The abundances of the stable molecules N 2 , O 2 , NO, N 2 O and NO 2 have been measured by means of a combination of infrared tunable diode laser absorption spectroscopy and mass spectrometry.A gas phase chemical kinetics model was developed in chemkin to investigate the contribution of homogeneous interactions to the convers… Show more

“…rad (also dimensionless) is the average radical yield per ion yield; a typical value rad ∼ 5 has been assumed [27]. Finally, if a 10% yield for NO formation from N 2 and O 2 is additionally taken into account [29,30] an estimation of the amount of radicals available to enter the water can be obtained:…”

“…Without taking wall association reactions into account only 10% of the observed NO density is calculated. The surface produced flow of, for example, NO turns out to be between 0.5 and 1 slm depending on the ratio of admixed nitrogen and oxygen [44].…”

“…Provided the injected power values would be sufficiently low enough surface processes could play a more dominant role. The importance of surface reactions for the formation of molecules by recombination has been experimentally demonstrated in a N 2 /O 2 plasma [14,15].…”
