Reticulated vitreous carbon (RVC) electrodes coated with platinum are used in gas phase non-thermal plasma for the removal of NO and NO2 in the presence of ethylene and water vapor. RVC is a relatively pure form of glassy carbon having high electrical conductivity, large macroscopic porosity, low microscopic porosity, and very sharp edges on the interconnected segments. When a pulsed high voltage electric field is applied to an RVC electrode, uniform plasma is produced in the cross-section of the reactor, and gas can flow uniformly through this active region of the plasma. The highest NOx removal efficiency in the present experiments was 0.2 moles/kWhr (60% removal) for the case with 5000 ppm ethylene in humid gas with 10 %O2 at 21°C.
