What is a catalyst of CFC?

Chlorofluorocarbons (CFCs) are not catalysts themselves; rather, they are compounds that can act as ozone-depleting substances in the atmosphere. In the presence of ultraviolet (UV) light, CFCs release chlorine atoms, which catalyze the breakdown of ozone (O3) molecules into oxygen (O2), significantly depleting the ozone layer. This reaction occurs in a cycle where a single chlorine atom can destroy thousands of ozone molecules before being removed from the atmosphere.
