Abstract: A photolytic and photocatalytic reaction enhancement device comprising a fluid permeable fixed-substrate material preferably constructed of either pure titanium or tungsten or their alloys that is oxidized or anodized to form a titanium dioxide or tungsten oxide layer, respectively, or a corrosion-resistant metal alloy that can be coated with a photocatalyst. The substrate may be a glass, polymeric or ceramic composition containing micropores, channels or conduits which receive oxidizing, reducing and/or pH agents and is more generally comprised of a length of mesh or cloth-like material which is folded in accordion-shaped fashion. A plurality of panels are created by the folding, each being adapted with at least one aperture for the slidable reception of the UV light source there through. The subject device may be removably installed within conventional and more novel, commercially available UV chambers without modification thereof or the use of invasive mounting means.
