Titanium dioxide, TiO 2 nanoparticles were synthesized via microemulsion method employing Triton X‐100 as the surfactant. Heat treatment was used to remove residual organic entities and also to produce anatase TiO 2 . Iron (Fe) was incorporated by wet impregnation into the TiO 2 nanoparticles in order to shift the active region of the photocatalyst from UV into visible region. The Fe/TiO 2 photocatalyst was characterized and their performance on the degradation of aqueous diisopropanolamine solution was compared with the commercial TiO 2 . The optimum conditions for the photodegradation of aqueous diisopropanolamine were found to be at 0.2 wt% of Fe. The present synthesized Fe/TiO 2 photocatalyst showed an improved performance over the commercial TiO 2 on the COD removal.
