Beschreibung
Zusammenfassung:	UV resistant inorganic coatings which exhibit photochemical activity that destroys toxic biological and chemical agents are disclosed. The inorganic coatings include semiconductor metal oxide nanoparticles that are photo-chemically active dispersed in an inorganic binder. In one embodiment, anatase titanium dioxide nanoparticles are dispersed in a silicon dioxide or silicate binder. Applications may include spacecraft, aircraft, ships, military vehicles, high value equipment and buildings such as subway stations, hospitals, railroad stations and stadiums.
