| Description | Deposit formation from air-toluene mixture was evaluated on a coplanar dielectric barrier discharge at atmospheric pressure. Alumina ceramics, alumina with TiO2 coating and alumina with high permittivity layer coating were examined at various electrode configurations. In general higher discharge input power led to reduction of solid deposition on the ceramics surface. TiO2-coated alumina exhibited substantially smaller deposit formation rate. This is explained by the presence of TiO2 photocatalytic effect and by the change of discharge microfilament dynamics. |
