Direct Partial Oxidation of Methane at Plasma-Catalyst-Liquid Interfaces
indicates competitive efficiency for electrified methane upgrading. Plasma diagnostics, including charge-voltage Lissajous analysis, optical emission spectroscopy, and plasma modeling, reveal a complex mechanistic picture where CuO-stabilized biradical coupling, gas-phase radical recombination, and vibrationally "hot" methane compete for overall reaction selectivity as a function of the pulsed plasma discharge. This study demonstrates the importance of modulating plasma chemistry and transport between plasma, catalyst, and liquid to improve reaction outcomes under complex multiphase environments.
