摘要:  Provided is a titanium oxide dispersion liquid that has dispersibility and dispersion stability both at superior levels and, when applied and dried, can form a photocatalyst coating film capable of rapidly developing excellent photocatalytic activity. The titanium oxide dispersion liquid according to the present invention includes titanium oxide particles (A), a dispersing agent (B), and a solvent (C). The titanium oxide particles (A) support a transition metal compound. The dispersing agent (B) includes a poly(acrylic acid) or a salt thereof. The poly(acrylic acid) or a salt thereof in the dispersing agent (B) preferably includes a poly(acrylic acid) alkali metal salt. The poly(acrylic acid) or a salt thereof in the dispersing agent (B) preferably has a weight-average molecular weight of from 1000 to 100000.
主权项:  A titanium oxide dispersion liquid comprising: titanium oxide particles (A) supporting an iron compound, wherein the titanium oxide particles are selected from the group consisting of: rutile titanium dioxide having (110) and (111) planes, supporting the iron compound on the (111) plane; rutile titanium dioxide having (110), (111), and (001) planes, supporting the iron compound on the (111) and (001) planes; and mixtures thereof, and wherein the supported amount of the iron compound is 50 ppm or more on a weight basis relative to the titanium oxide particles; a dispersing agent (B) comprising a poly(acrylic acid) or a salt of the poly(acrylic acid); and a solvent (C).
