Ozone generation and destruction on ozonizer electrode surfaces

abstract

English

The reactions of ozone and oxygen with electrode surfaces in an ozonizér were studied. Atomic oxygen can be adsorbed on electrode surface in the discharge or by ozone action. The adsorbed oxygen can then react with molecular oxygen from gas phase producing ozone. Also the ozone can react with adsorbed atomic oxygen or with free active site on the surface, both reactions lead to ozone destruction. The ozone creation on surface is faster than the ozone destruction, which prevails in longer times. In experiment the electrode surfaces in ozonizer were treated by ozone (without discharge). Then the ozonizer was filled by oxygen, which was reacting with adsorbed oxygen atoms for given reaction time. The concentration of produced ozone was measured by absorption spectroscopy. It was found the ozone concentration decreases with increasing reaction time.
