Background and Objectives: Photocatalytic oxidation (PCO) is a promising method for the removal of volatile organic compounds (VOCs). Photocatalytic oxidation process, despite its advantages, has disadvantages such as deactivation of photocatalyst. The deactivated photocatalyst can be active through thermal abatement, ozonation, exposure with clean air and UV radiation. Materials and M...
