AB: Understanding the oxidation mechanisms of volatile and semivolatile organic compounds (VOCs and SVOCs) is critical to assess their environmental fate, and to design efficient indoor air cleaning technologies. Ozone-driven oxidation of gas phase and surface-bound indoor chemicals generates potentially harmful partially oxidized byproducts and ultrafine particulate matter. The composition of chemically complex secondary aerosol particles formed during ozonation has been only partially elucidated. Air cleaning technologies relying on photocatalytic oxidation of VOCs have the potential to improve indoor air quality in buildings in a cost-effective way. Current research on this area focuses on the development of novel materials that can improve the VOC conversion efficiency and mineralization yields over an extended catalyst lifetime.
