Abstract
A photocatalytic structure according to one embodiment of the present invention, which achieves a high deodorization effect, comprises a base material formed of a porous ceramic material in a platelike shape and a photocatalyst supported on the surface and inside pores of the base material. The open porosity of the ceramic material is 35-75%, the ceramic material includes large pores having a diameter of 100-1000 μm inclusive, and small pores having a diameter of 10 μm or less are open in the inner wall surfaces of the large pores.
Claims5
A photocatalytic structure comprising:
- a base material formed of a porous ceramic material in a platelike shape;
- and
- a photocatalyst supported on a surface and inside pores of the base material, wherein
- the ceramic material has an open porosity of 35% or more and 75% or less, the ceramic material has large pores each having a diameter of 100 μm or more and 1000 μm or less, and
- small pores each having a diameter of 10 μm or less are open to inner wall surfaces of the large pores.
A method for producing a photocatalytic structure, the method comprising:
- immersing a base material formed of a porous ceramic material in a platelike shape, in a photocatalyst dispersion liquid in which photocatalyst particles are dispersed in a solvent;
- drying the base material;
- and
- baking the base material, wherein
- the ceramic material has an open porosity of 35% or more and 75% or less,
- the ceramic material has large pores each having a diameter of 100 μm or more and 1000 μm or less, and
- small pores each having a diameter of 10 μm or less are open to inner wall surfaces of the large pores.
