Abstract

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.

摘要

挥发性有机化合物（VOCs）是典型的室内空气污染物，因其毒性会对人体产生负面影响。去除VOCs最有前景的方法之一是使用TiO进行光催化降解。在本研究中，如前所述，研究了添加炭黑（CB）和重金属纳米颗粒（NPs）以提高结合超声雾化和紫外线照射的TiO基光催化VOC分解系统的效率。添加CB和Ag NPs显著提高了降解效率。还讨论了与其他重金属纳米颗粒的比较及其各自的作用。
