The positive corona discharge has been generated in a reactor equipped with a system of stainless steel cylindrical coaxial electrodes. The discharge has been fed with mixtures of carbon dioxide and oxygen (0–100% of oxygen) in flow-stopped regime. The time dependence of discharge current has been measured for a period of 1 h. The effect of the mixture composition on the discharge current and the onset voltage of the discharge has been investigated. A slight increase in the onset voltage was observed with increasing amount of oxygen in the gas mixture up to 20% of oxygen, where the maximum was reached. Then, with further increase of oxygen concentration, the onset voltage decreased. These results correspond to the measured discharge currents. The lowest currents were observed for a mixture containing 20% of oxygen, where the onset voltage is highest, and the highest currents were observed for pure oxygen, where the onset voltage is lowest. These observations are in agreement with Townsend's formula expressing the current–voltage characteristics of the discharge.
