Abstract:
1. A photocatalytic device, comprising: a cylindrical housing having an inlet opening and an outlet opening; one or more catalyst substrates disposed within the cylindrical housing and adapted to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions, the one or more catalyst substrates comprising a hydrated multi-metallic catalyst having two or more elements selected from the group: Titanium dioxide, Platinum, Gold, Silver, Copper, Rhodium, Ruthenium, and Lanthanum; an ultraviolet light source disposed within the cylindrical housing and adapted to provide the ultraviolet light to the one or more catalyst substrates; and a fan disposed within the cylindrical housing and adapted to cause air to enter the cylindrical housing via the inlet opening, circulate through the one or more catalyst substrates within the cylindrical housing, and exit the cylindrical housing via the outlet opening.
