Fig. 5: Reaction fluxes vs plasma conditions.
From: Observation and rationalization of nitrogen oxidation enabled only by coupled plasma and catalyst
Steady-state reaction flux of N2 oxidation on Pt(211) in a integral reactor at 873 K with (a) \({P}_{{{{{{{{\rm{N}}}}}}}}}=2\times 1{0}^{-2}{P}_{{{{\rm{N}}}}_{2}}\) and Tvib = 1000 K, (b) \({P}_{{{{{{{{\rm{N}}}}}}}}}=2\times 1{0}^{-2}{P}_{{{{\rm{N}}}}_{2}}\) and Tvib = 10000 K, (c) \({P}_{{{{{{{{\rm{N}}}}}}}}}=2\times 1{0}^{-11}{P}_{{{{\rm{N}}}}_{2}}\) and Tvib = 1000 K, and (d) \({P}_{{{{{{{{\rm{N}}}}}}}}}=2\times 1{0}^{-11}{P}_{{{{\rm{N}}}}_{2}}\) and Tvib = 10000 K, presented as Sankey diagrams, in which each segment indicates a reaction and the corresponding segment width qualitatively indicates the value of the rate normalized to the NO production rate. Solid lines represent reactions involving catalytic sites and dotted lines represent plasma processes. Blue, gold and red mean intermediate, productive and unproductive routes, respectively. The reaction conditions are consistent with the four corners of Fig. 4d.
