Abstract

Nowadays, indoor air pollution has emerged as a major health concern for the indoor living population. UV photocatalytic indoor air cleansing has been found to be a promising technology. Effective UV photocatalysts have been applied to monitor/control the indoor air quality (IAQ) level. The nanomaterials based on nanocarbons, polymers, and nanoparticles have been applied in the UV photocatalysts. Indoor pollutants including gaseous pollutants, organic compounds, and biological pollutants have been removed using photocatalytic technology. Basically, nanomaterials act to degrade the environmental pollutants into environmentally safe forms, i.e., least hazardous for human health and maintain the IAQ level. Accordingly, through the use of nanomaterial-based UV photocatalysts, future solutions linking the IAQ regulation to the novel nanomaterials have been achieved.
