Visible-Light Photodegradation of Diisopropanolamine using Bimetallic Cu-Fe/TiO2 photocatalyst

Visible-Light Photodegradation of Diisopropanolamine using Bimetallic Cu-Fe/TiO2 photocatalyst

Titania nanoparticles, TiO2 were synthesized via microemulsion method prior to monometallic (Fe, Cu) or bimetallic (Cu−Fe) incorporation using wet impregnation method. The prepared photocatalysts were characterized using X-ray diffraction, field emission scanning electron microscopy, diffuse refl...
