Cu-Fe/TiO₂ Photocatalyst for Deep Desulfurization Process

Abstract:

A series of Cu-Fe/TiO₂ photocatalysts were prepared and calcined at 400°C and 500°C for 1 h. The photocatalysts were characterized using diffuse reflectance spectroscopy (DR-UV-Vis), X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). The performance for sulfur removal was carried out using model oil containing 100 ppm S (from dibenzothiophene). The highly dispersed Cu-Fe/TiO₂ photocatalyst displayed mainly spherical shaped particles. The best performing photocatalyst was 0.8wt% Cu-Fe loading and calcined at 400°C (0.8wt400) giving 18% sulfur removal. The band gap for 0.8wt400 was lowered to 2.96 eV compared to 3.21 eV for TiO₂.
