Photocatalytic Oxidative Desulfurization of Model Oil Using Cu/TiO2 Photocatalyst and Eutectic Based Ionic Liquid: Effect of Metal Loading

Titanium dioxide (TiO2) photocatalyts doped with copper metal at different metal loadings were successfully prepared and characterized. Photocatalytic oxidative desulfurization of model oil containing dibenzothiophene as the sulfur compound (100 ppm) was investigated using the prepared photocatalyst. The photocatalyst with 2.0 wt% Cu metal loading showed the best sulfur removal at 66.25%.
