The effect of N2+O2 mixture on ozone production has been investigated. The maximum production of ozone was already corresponding to 70% of oxygen in the gas mixture for any applied voltage from 4,5 to 7 Kv. Experimental set up: Figure 1 shows the different parts of the experimental used. Figure 3. Electric current vs oxygen percentage A B Figure 1. Schematic of the experimental set-up. Figure 2.
