Temperature dependence of the rate of formation of active species in nanosecond streamer corona discharge between a solid electrode and water surface

摘要

The dependence of the yield of ozone in a nanosecond streamer electric corona discharge in the presence of oxygen and water vapor on temperature over the range 25-66 degrees C was examined. It was found that the yield decreased to zero with an increase in temperature to 66 degrees C. The decrease in the yield can be explained in terms of an increase of water vapor concentration in the discharge gap at elevated temperatures, as well as by an increase in the water ionization constant.
