Abstract
The photocatalyst granules of the present invention are photocatalyst granules prepared by molding a mixture containing photocatalyst particles and colloidal silica, and drying the molded mixture, wherein the content of the photocatalyst particles in the photocatalyst granules is 10% by weight or more. According to the photocatalyst granules of the present invention, since contact between the photocatalyst particles and the open air is not inhibited, thereby enabling the photocatalyst particles to contact with an organic matter sufficiently, oxygen or ultraviolet light, the photocatalytic activity is high. That is, the photocatalyst granules of the present invention are easy to handle and can be fixed on a solid, and also have excellent durability and high photocatalytic activity.
