Abstract
A photo-bio hybrid system was developed using iron oxide nanocomposite thin film as photocatalyst and cell debris and crude cell extract enzyme as biocatalyst. The iron oxide nanocomposite was prepared by a sol-gel approach and coated on glass by spin-coating technique. The nanocomposite has photocatalytic property, which is used under very mild reaction conditions. The iron oxide nanocomposites were characterized by X-ray diffraction (XRD), Fourier transmission infrared (FT-IR), UV–Vis spectroscopy (DRS), and field emission scanning electron microscopy (FESEM). Advance oxidative desulfurization using iron oxide nanocomposite thin film as photocatalyst and cell debris and crude cell extract enzyme as biocatalyst showed that 83% efficiency for desulfurization of dibenzothiophene as a model sulfur compound. These results suggest that use of the constructed nanobiotechnology can be transformed into green technology.
