Evaluating Discharge Performance and Catalytic Properties of Nanoscale Catalyst Dielectric Barrier Discharge System

Abstract

Abstract Dielectric barrier discharge (DBD), a non-thermal plasma(NTP)technology, has a wide range of environmental applications. In this study, TiO2, SiO2, and Al2O3 were coated on the surface of a quartz dielectric using a dip-coating method. The catalyst coating coatings effectively improved the local discharge intensity, thus enhancing the generation of reactive species. After discharge by the DBD system, the O atom in the middle of TiO2 crystal is replaced by N atom doping, and the Al = O and Al OH groups on the surface of Al2O3 increase. All Catalyst coating surfaces contained a small number of hydroxyl groups. TiO2 and Al2O3 surfaces had fewer oxygen vacancies. thus making O3 synthesis dominant at the gas–solid interface.
