Volatile organic compounds (VOCs) are representative indoor air pollutants that negatively affect the human body owing to their toxicity. One of the most promising methods for VOC removal is photocatalytic degradation using TiO. In this study, the addition of carbon black (CB) and Heavy Metal nanoparticles (NPs) was investigated to improve the efficiency of a TiO-based photocatalytic VOC decomposition system combined with ultrasonic atomization and ultraviolet irradiation, as described previously. The addition of CB and Ag NPs significantly improved the degradation efficiency. A comparison with other Heavy Metal nanoparticles and their respective roles are discussed.
