Abstract:
A method for producing a composite composed of a mixture containing a metal oxide derived from a metal fluoro complex compound, which comprises adding a fluoride ion-capturing agent to an aqueous solution containing the metal fluoro complex compound to precipitate the composite, wherein said composite is in the form of a film precipitated on a substrate immersed in the aqueous solution and said composite is selected from the group consisting of: a mixture of two or more metal oxides wherein one of the metal oxides comprises a photocatalytic titanium oxide; one or more metal oxides containing micro-particles wherein one of said one or more metal oxides comprises a photocatalytic titanium oxide; and one or more metal oxides doped with ions of at least one metal, wherein one of said one or more metal oxides comprises a photocatytic titanium oxide.
