    Plasma-Catalyst Interactions

    Low-temperature catalytic reactions induced by nonthermal plasma (NTP) have been of great interest in plasma chemistry. The presence of plasma can alter the elementary steps in catalysis. The type of catalysts...

    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 ...

    Effect of zeolite in surface discharge plasma on the decomposition of toluene

    Toluene was decomposed in a surface discharge plasma reactor packed with various zeolites. The positioning effect of the zeolite bed was also investigated Reactor-B, in which the zeolite bed was located upstre...
