The prepared photocatalysts were characterized using X-ray diffraction, field emission scanning electron microscopy, diffuse reflectance UV-Vis spectroscopy and point of zero charge. The addition of metals, especially Cu enhanced the absorbance in the visible region. The lowest band gap was observed for the bimetallic Cu-Fe/TiO2 (2.77 eV) compared to bare TiO2 (3.05 eV). The performance of the photocatalysts for photodegradation of diisopropanolamine (DIPA) at pH 8 was determined using a batch glass reactor under simulated sunlight (980 W/m2). The best performance was displayed by Cu-Fe/TiO2 with the highest DIPA removal of 92. © (2014) Trans Tech Publications, Switzerland. %Z cited By 3; Conference of 1st International Materials, Industrial, and Manufacturing Engineering Conference, MIMEC 2013 ; Conference Date: 4 December 2013 Through 6 December 2013; Conference Code:101778
