After the air is polluted, containing harmful inorganic gases, organic gases, and particulate matter. Such as ammonia (NH3), hydrogen sulfide (H2S), formaldehyde (HCHO), benzene (C6H6), carbon monoxide (CO), methane (CH4) and other ozone reactions with these contaminants for example as follows:

 

2NH3 + O3 = 3H2O + N2

 

C6H6 + 5O3 = 3H2O + 6CO2

 

2HCHO + 2O3 = 2H2O + 2CO2 + O2

 

CO + O3 = CO2 + O2

 

CH4 + 2O3 = CO2 + O2 + 2H20

 

The reaction described above ozone decomposition of harmful gases.
