An increasing number of air pollutants, like haze, have aroused people's great concern about the indoor air quality. Ozone is one of the key factors influencing indoor air quality. In this paper, according to the recent research on indoor ozone pollution at home and abroad, the sources of indoor ozone and indoor pollution are analyzed and reviewed, and some current methods and technologies for ozone purification are discussed. Finally, based on the above presentation, some more efficient and practical multiphase thermal catalysts are suggested to be developed for ozone purification.
