Oxidation of propene from air by atmospheric plasma-catalytic hybrid system [PDF]

Journal of the Serbian Chemical Society, 2018
The pulsed dielectric barrier discharge (DBD) combined with the palladium supported on alumina beads, was investigated for propene (C3H6) removal from air. The effects of thermal-catalysis, plasma-catalysis (in-plasma catalysis and post-plasma catalysis),

Effective reduction of N2O emission via combined plasma catalysis

Catalysis Communications, 2023
N2O is a potent greenhouse gas that also causes devastating effects on the ozone layer. In this study, N2O decomposition is evaluated via thermal catalysis, plasma-alone and plasma catalysis, respectively. In thermal catalysis, N2O decomposition achieved
