Abstract
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.
Claims5
