Abstract A novel atmospheric pressure plasma apparatus (APPA) is designed with a liquid electrode, and its discharging characteristics are studied. Relatively uniform and intense discharge can be realized in the APPA system. An experimental study on removal of NO molecules is carried out by using the APPA, and more than 95.5% of NO is decomposed when the NO initial concentration is lower than 400ppm. Removal of NO efficiency increases rapidly with the increasing discharge power. Compared with the absence of O2, more NO2 is generated with the increase of O2 concentration. However, most of the NO molecules are decomposed to N2 and O2 directly, when O2 concentration changes from 0 to 1.1vol%.
