Photocatalytic degradation of atmospheric fine particulate matter (PM) collected on TiO supporting quartz fibre filter.

Carbonaceous constituents in fine particulate matter (PM) are often associated with adverse health effects in humans. Although air filtration technology is widely used for preventing exposure to PM, the trapped PM still has hazardous property if not treated subsequently. Thus, this study aimed to realise detoxification of PM with a photocatalytic decomposition of carbonaceous compounds in PM samples collected on a quartz fibre filter coated with titanium dioxide (TiO).
