TAILCHEM

The TAILCHEM project aims to find out whether a higher selectivity of plasma-chemical processes at high pressures is possible by changing the high-voltage waveform. The applied voltage waveform is intended to change the reduced electric field strength over time in such a way, that different electron impact processes dominate in the different development phases of a gas discharge and thus couple the energy in a more tailored way. The model system in the project is the formation of nitrogen oxides in air, which is also of industrial importance for so-called nitrogen fixation. The selective generation of reactive nitrogen species is to be achieved in particular by vibrationally excited nitrogen in the ground state. In addition to gas conversion, this task also requires high-end plasma diagnostics in order to correlate the discharge physics with this.

The project is funded by the EU under Marie-Skłodowska-Curie Actions and runs from 2024 to 2026.
