No tests have been done on whether ozone can kill novel coronaviruses. When UV light is used to irradiate the environment, a byproduct is produced, namely ozone. However, the direct action of UV light is the main factor in killing the virus, not the action of ozone. Therefore, ozone is only a byproduct of UV sterilization. If you want to sterilize the environment, you should still consider the use of UV lamps. Whether ozone has such an effect, or how it works, is subject to further research and certification.
