Plasma-driven in situ H2O2 generation offers a potential sustainable route for oxidative biotransformations, but its application has been hindered by challenges such as insufficient H2O2 production and enzyme degradation from direct plasma...
The elementary processes during the fixation of nitrogen by plasma catalysis are studied in a low-pressure plasma experiment with N$_2$ and O$_2$ as source gases. The formation of surface groups on an iron oxide foil is monitored with infrared...
Data of figures for the paper titled "Synergistic control of radical generation in a radio-frequency atmospheric-pressure plasma jet via voltage waveform tailoring and structured electrodes"
Pulse modulation of an RF-driven atmospheric pressure plasma jets (APPJs) can be used to control the production of short-lived and long-lived species. This was applied for the production of H2O2 by a humidified He APPJ operating at 13.56 MHz. In...
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...
This study is focused on measuring the densities of the excited molecular oxygen species, O2(a1∆g) and O2(b1Σ+g), produced in a COST atmospheric pressure plasma jet using a helium-oxygen mixture. Knowledge of the ozone density is critical for...
Nanosecond and microsecond plasma-in liquid systems are explored to oxidize or regenerate a copper oxide surface in situ to serve as a catalyst for electrochemical CO2 conversion. The plasma excitation generates H2O2 in the liquid, which induces...
The ion energy distribution functions (IEDF) have been measured for a helium atmospheric pressure dielectric barrier discharge jet expanding into the air and impacting a metal or ceramic surface. The plasma jet produces ionization waves as guided...
Catalysts are a critical component for chemical reactions in industrial applications. They are able to optimize selectivity, efficiency and reactions rates thus enabling more environmentally friendly processes. This work presents a novel approach...
Plasma liquid interactions are important for a range of applications. For these, H2O2 and OH represent two key reactive species, whose concentrations in liquids need to be controlled for effective application outcomes. Here, a combination of gas...
