Patent ID: 7988923

Claim:
A photohydroionization cell comprising: an ultraviolet light source for providing broad spectrum ultraviolet light in the 100 nm to 300 nm range; and a one-piece catalytic target structure mechanically coupled to and substantially surrounding the ultraviolet light source, the catalytic target structure including: a surface that, after contact with ultraviolet light, reacts with hydrate at the surface to form advanced oxidation product, the surface having a repeating V-shaped geometry comprising a plurality of V-shaped pleatings that generally surround a circumference of the ultraviolet light source, the plurality of V-shaped pleatings including: (i) apexes formed by panels of the catalytic target structure that converge to point away from the ultraviolet light source and (ii) tips formed by panels of the catalytic target structure that converge and point towards the ultraviolet light energy source; and a plurality of holes configured to allow passage of both surrounding gases and a portion of the ultraviolet light through the target structure, wherein the holes are arranged in rows that extend linearly in a longitudinal direction along the length of the panels that form the apexes and the tips of the plurality of V-shaped pleatings.
