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

摘要

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 onto the catalyst surface by O2 plasma was approximately proportional to the square of the amount of supported silver. In dry air, its extraordinary long lifetime was confirmed for the first time.
