A Review of the Photocatalytic Degradation of Volatile Organic Compounds (VOCs) in Indoor Air

摘要

Indoor air quality (IAQ) has received increased attention as people spend more and more time indoors. Presently, people spend about 88% time of their indoors (Jones, 1999). This means that the indoor environment plays a very important role in human health. Among all types of indoor air pollutants, volatile organic compounds (VOCs) have received a great deal of attention from researchers, as many VOCs are carcinogenic, mutagenic, or teratogenic (Alberici and Jardim, 1997). Some typical VOCs present in indoor environment are summarized in Table 1.
