    Study of Plasma-Induced Surface Active Oxygen on Zeolite-Supported Silver Nanoparticles

    Surface oxygen induced by non-thermal plasma at atmospheric pressure on silver nanoparticle-loaded zeolite was determined by a chemical probe based on the oxidation of NO. The amount of active oxygen fixed ont...

    Oxygen Isotope (18O2) Evidence on the Role of Oxygen in the Plasma-Driven Catalysis of VOC Oxidation

    This paper reports isotopic evidence on nonthermal plasma-induced fixation of gas-phase oxygen on the surface of several catalysts such as TiO2, Ag/TiO2, Ag/γ-Al2O3 and Ag/MS-13X at atmospheric-pressure. On-line ...
