Abstract

“Titanium dioxide: Environmental white knight?" titled Frazer on the Innovations page of Environmental Health Perspectives in 2001: the article described possible advantages of different photocatalytic and self-cleaning materials, like tiles and pavement blocks. Almost two decades have passed, and many advances have been made in understanding the mechanisms of TiO2 photoactivity and in developing its potential in addressing environmental issues. This chapter will provide a short overview of these mechanisms, focusing then on construction materials modified through the addition of titanium dioxide nanoparticles. Examples will be given of laboratory experiments carried out in the recent years, and of current applications in the built environment; attention will also be paid to the international standards that have been, and are still being, developed for this technology.
