摘要：
The invention relates to a process for producing an iron-containing photocatalyst based on titanium dioxide. The photocatalyst is produced by introducing iron(III) ions into an aqueous suspension of titanium oxide hydrate nanoparticles, subsequently precipitating iron(III) hydrate, separating off the mixture of titanium oxide hydrate and iron(III) hydrate and heat treating it at a temperature of at least 100°C: the photocatalyst produced by the process of the invention is photoactive both in the UV region and in the visible spectral region.
