A catalytic device comprises a mixed structure of photocatalyst and silica. The mixed structure may be comprised of alternating layers of photocatalyst and silica, a layer having a uniform mixture of photocatalyst particles and silica particles, or a layer having a graded mixture of photocatalyst particles and silica particles.

Photocatalytic device with mixed photocatalyst/silica structure

A photocatalyst system for volatile organic compounds with two parts that include a photocatalyst layer on a substrate and a porous overlayer. The photocatalyst layer is reactive with volatile organic compounds when UV light is projected on it. The overlayer is situated on the photocatalyst layer. The overlayer is UV transparent and has an interconnected pore network that allows contaminated air to pass through the overlayer. The size and the shape of the interconnected pores acts to selectively exclude certain contaminants that can deactivate the photocatalyst.
