In the stratosphere, ozone (O3) naturally cycles to oxygen gas (O2) and back when it absorbs solar energy (the Chapman cycle). When CFCs are present, sunlight releases chlorine atoms that catalytically convert O3 to O2: Cl reacts with O3 to form ClO and O2, and ClO is then converted back to Cl, which can destroy further ozone. The net result is more oxygen and less ozone.
