Abstract

Abstract : In the present work, ZrO2 nanoparticles loaded on glass wool (GW) were employed for catalytic and plasma‐catalytic decomposition of ethylene. Unlike ZrO2 pellets, nanosized ZrO2 was found to exhibit catalytic activity for the decomposition of ethylene. Some carbon‐containing by‐products like CH4, C2 H2, and HCHO were detected under room‐temperature operation of the reactor. The formations of such unwanted by‐products were suppressed and the conversion into CO2 was enhanced when the ZrO2 catalyst was combined with non‐thermal plasma at high temperatures. The nanosized ZrO2 exhibited a stable decomposition performance during 80‐h continuous operation, suggesting that it is able to withstand deactivation without substantial loss in its catalytic activity. Abstract : Nanosized ZrO 2 acts as a catalyst for non‐thermal plasma decomposition of volatile organic compound . Unlike ZrO2 pellets, nanosized ZrO2 is found to exhibit catalytic activity for the decomposition of ethylene, and it shows stable decomposition performance even after 80‐h continuous operation, suggesting that it is able to withstand deactivation without substantial loss in its catalytic activity, which is an important criterion for industrial applications.
