PHOTOCATALYTIC DEVICE, IRRADIATION METHOD OF EXCITING LIGHT, METHOD FOR DECOMPOSING OBJECT TO BE DECOMPOSED AND USE OF THE PHOTOCATALYTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a photocatalytic device capable of obtaining a high photocatalytic result by utilizing exciting light efficiently.

SOLUTION: This photocatalytic device 1 is provided with: a main body 2 which is formed by alternately layering a plurality of plate-shaped photocatalyst-deposited bodies 4 and a plurality of diffusion plates 5, each of which is constituted so that the light entering from one end thereof is diffused by a diffusing factor arranged on the optional surface thereof and the diffused light is leaked, while securing a passable space of a fluid containing the object to be decomposed and has an incident light inlet 6 formed by bundling one end of each of the plurality of diffusion plates; and an exciting light source 3 arranged so that exciting light can be made incident on the incident light inlet of the main body.
