Fig. 4: Plasma vs plasma-catalytic NO production.
From: Observation and rationalization of nitrogen oxidation enabled only by coupled plasma and catalyst
Schematic representations of integral reactor models for (a) plasma reactions and (b) plasma catalytic reactions, respectively. Outlet NO concentrations (ppm) of (c) plasma reactions and (d) plasma catalytic reactions against Tvib and PN at 873 K, where the inlet pressures of N2 and O2 are 4.995 and 0.005 mbar, respectively. The residence times are 0.28 s and 6.4 μs in (a) and (b), respectively. The number of active Pt sites is 230 nmol. e The ratio of NO produced in (d) and (c).
