Performance of Surfactant Assisted Synthesis of Fe/TiO2 on the Photodegradation of Diisopropanolamine

Titanium dioxide, TiO2 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 TiO2. Iron (Fe) was incorporated by wet impregnation into the TiO2 nanoparticles in order to shift the active region of the photocatalyst from UV into visible region. The Fe/TiO2 photocatalyst was characterized and their performance on the degradation of aqueous diisopropanolamine solution was compared with the commercial TiO2. The optimum conditions for the photodegradation of aqueous diisopropanolamine were found to be at 0.2 wt% of Fe. The present synthesized Fe/TiO2 photocatalyst showed an improved performance over the commercial TiO2 on the COD removal.
