Abstract

The photocatalytic activity of micro- and nano-titanium dioxide (TiO2) has been utilized to significantly improve the degradation efficiencies of various contaminants in both water treatment and air pollution control. This article is a review of the literature covering current research on environmental applications of micro and nano-TiO2. The mechanisms of contaminant degradation of nanoparticle TiO2 are reviewed, and its special properties are compared to micro-sized TiO2 in air purfication and water treatment.
