Photocatalytic device with curved reflectors

摘要

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.

1. A photocatalytic device, comprising:
an ultraviolet light source; one or more catalyst substrates adapted to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions; and a plurality of convex reflectors positioned adjacent to the one or more catalyst substrates, with the ultraviolet light source positioned between the convex reflectors, a convex face of each of the convex reflectors having a shape adapted to face the ultraviolet light source and to distribute reflected light from the ultraviolet light source across a surface of the one or more catalyst substrates.
