A low-pressure double-inductively coupled plasma device is used to study the fundamental plasma parameters, plasma chemistry, and UV photon emission from the first excited state of nitric oxide, NO(A), in gas mixtures of nitrogen and oxygen. In...
A Direct Current (DC) nanosecond (ns)-pulsed plasma jet fed with N2 at near atmospheric pressure (20 000 Pa) is studied using a transient zero-dimensional (0-D) model coupled with a two-term Boltzmann equation solver. Good agreement is observed...
This study investigates the correlation between flow fields induced by a surface dielectric barrier discharge (SDBD) system and its application for the volatile organic compound gas conversion process. As a benchmark molecule, the conversion of n...
Hydrogen production via plasma methane pyrolysis is investigated using a microwave plasma torch (MPT) and a gliding arc plasmatron (GAP). The performance of the two plasma sources in terms of methane conversion, product spectrum, and energy...
NO synthesis using plasma catalysis is analyzed in a parallel-plate atmospheric pressure RF plasma from N$_2$/O$_2$ admixed to helium exposed to Fe and Pt catalysts on a SiO$_2$ support. The NO$_x$ species are measured by Fourier-transform...
Dielectric barrier discharges (DBD) are often used for gas conversion, such as carbon dioxide splitting, volatile organic compound removal or ozone generation. Due to the tiny plasma filaments in DBD discharges, efficient mixing of the gas flow...
The plasma catalytic oxidation of n-butane diluted in a helium-oxygen RF plasma jet is used to study volatile organic compound (VOC) removal to unravel plasma catalytic synergisms. The plasma conversion is tested for a stoichiometric n-butane...
The in-plasma-catalytic synthesis of ammonia from nitrogen and hydrogen admixed to a helium RF plasma is studied with infrared absorption spectroscopy, optical emission spectroscopy, and through chemical kinetics modeling. Sandblasted glass is...
Atmospheric pressure plasmas are widely used for nitrogen fixation processes to produce ammonia NH3 or nitrogen oxides NOx , including for example nitrite NO2– or nitrate NO3–. Small scale atmospheric pressure plasma jets (APPJs) can provide the...
In this work, the transport of hydroxyl radicals and hydrogen peroxide from a humid atmospheric pressure plasma jet into plasma-treated liquids is analysed. The concentration of H2O2 was measured by a spectrophotometric approach using the reagent...
