CATALYTIC DESTRUCTION OF OZONE
Ozone’s ability to absorb UV radiation also
means that it is unstable, and it react easily
with compounds found in the stratosphere
that have been released by humanbeings.
The most known dangerous ones are NOx
(NO, NO2) and chloro flurocarbons, known
as CFCs. The highly energized radicals are
formed from those compounds and then
catalyse the decomposition of ozone to
oxygen, which will produce the ozone
depletion.
Chloroflurocarbons were widely used in
aerosols, refrigirators, solvents, plastics due
to their low reactivity and low toxicity in the
troposphere. But when they get into the
stratosphere, the higher energy UV radiation
breaks them down, releasing free chlorine
atoms, which are also reactive free radicals.
