The present invention relates to a method for producing a titanium dioxide-based iron-containing photocatalyst. This photocatalyst adds iron (III) ions to an aqueous suspension of titanium oxide hydrate nanoparticles, followed by precipitation of iron (III) hydrate, titanium oxide hydrate and iron (III) hydrate Produced by separating the mixture from the product and heat treating at a temperature of at least 100 ° C .: The photocatalyst produced by the process according to the invention is photoactive both in the UV region and in the visible spectral region. |
