Abstract

Ozone output in ion wind devices using one or more emitters (10) and an array of collectors (20) (accelerators) may be reduced through catalytic conversion of the produced ozone back to oxygen by using various materials placed in or downstream from the airflow, such as a manganese dioxide coating on the accelerator substrate elements. Precious metal or activated carbon coatings may also be used for the purpose of converting ozone to oxygen.
