Some freons, not all, contain chlorine in their molecules. In the ozone layer, the intense radiation there knocks the chlorine off the molecule. Chlorine is the catalyst for ozone to oxygen reduction.
Freon is neither reactant, product, nor catalyst. It is strictly a very inert, chlorine delivery vehicle.
