光触媒塗布液、光触媒構造体及びその製造方法
Document Type and Number:
Japanese Patent JP6850348
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing: a photocatalyst application liquid which is for easily forming a photocatalyst layer that has excellent strength and exhibits sufficient photocatalytic activity, and a production method therefor; and a photocatalytic structure having a photocatalyst layer that has excellent strength and exhibits sufficient photocatalytic activity, and a production method therefor. This photocatalyst application liquid production method comprises: a step for mixing a hydrolysable silane compound represented by formula (1): Si(OR)4 (in the formula, each R represents an alkyl group having 1-4 carbon atoms, wherein the four R's may be the same or different from each other), a monovalent alcohol having 1-4 carbon atoms, an acid, water, and fine particles of a photocatalytic material so as to prepare a mixture wherein the contained amount of the hydrolysable silane compound is at most 5 mass% in SiO2 equivalent, and the molar ratio (water/hydrolysable group) between the hydrolysable group in the hydrolysable silane compound and the water is at least 8, and the contained amount of the monovalent alcohol having 1-4 carbon atoms is 20-50 mass%; and a step for subjecting the hydrolysable silane compound in the mixture to hydrolysis or hydrolytic condensation using the acid as a catalyst.
