PURPOSE: To cause a deodorizing material to demonstracte its deodorizing effect for a long time by providing a part or the whole of titanium oxide and an oxidization accelerator on the surface layer of an inorganic cured body. CONSTITUTION: An inorganic cured body is composed of an inorganic curing composition composed of at least one kind of cement, Synthetic calcium silicate, synthetic magnesium silicate and magnesium carbonate. A part or the whole of titanium oxide and an oxidiation accelerator is provided on the surface layer of the inorganic cured body. The kind of titanium oxide is not restricted, and titanium oxide for decomposing a malodorous substance as a catalyst in the existence of light can be used, and anatase type TiO2 fine powder is applicable. As for the oxidization accelerator, a substance to accelerate the catalyst action of titanium oxide can be used, and for example, transition metal, precious metal or the like can be used. Also a surface protection layer can be formed on the surface of the photocatalyst material. |
