The research focus is on the characterisation and analysis of pulsed plasmas inside liquids. The nanosecond and microsecond long plasmas are investigated by optical diagnostics like shadowgraphy, Schlieren imaging and optical emission and absorption spectroscopy. The created species inside the liquid can further modify metallic surfaces which are in direct contact with the liquid. These surface modifications are monitored with FTIR spectroscopy. By combining these diagnostics, we are able to describe the liquid plasmas from ignition to their influence on adjacent surfaces. With this, in-liquid plasma treatment of catalytic surfaces is investigated and optimised as a future application for improving the performance of catalytic surfaces used for CO2 conversion.
