Abstract
A photocatalytic device has an ultraviolet light source and a plurality of photocatalytic structures, such as hydrated quad-metallic catalyst surfaces. The photocatalytic device has curved reflectors that are positioned to reflect ultraviolet light against a face of the photocatalytic structures. The curved reflectors are shaped to minimize the distance traveled by the ultraviolet light between the light source and the photocatalytic structure. The curved reflector is further shaped to direct reflected ultraviolet against the surface of the photocatalytic structure in a perpendicular direction.
