Abstract:
1. A photocatalytic device, comprising: an ultraviolet light source; first and second catalyst substrates adapted to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions, the first and second catalyst substrates positioned on opposite sides of the ultraviolet light source such that a near surface of the first catalyst substrate faces a near surface of the second catalyst substrate, the near surfaces of the first and second catalyst substrates including openings to a plurality of fluted structures, the openings disposed in a direct line-of-sight of at least a portion of light emitted by the ultraviolet light source; and first and second convex reflectors positioned on opposite sides of the ultraviolet light source and between the first and second catalyst substrates, each of the convex reflectors having a convex surface adapted to reflect at least another portion of the light emitted by the ultraviolet light source directly across the openings of the fluted structures of the near surfaces of the first and second catalyst substrates, wherein the convex surfaces of the first and second convex reflectors face each other.
