title: Wheat bran valorisation: Towards photocatalytic nanomaterials for benzyl alcohol photo-oxidation.
abstract: In this work, we have successfully synthesized a set of titania photocatalytic nanocomposites by the incorporation of different TiO2content on wheat bran residues. The obtained catalysts were characterized by different techniques including UV-Vis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Transmission Electron Microscopy (TEM) while their photocatalytic activity was investigated in the oxidation of benzyl alcohol under UV light irradiation. Benzaldehyde yields were ca. 20%, with conversion in the systems of ca. 33% of benzyl alcohol by using 10%Ti-Bran catalyst, as compared to 33% yield to the target product (quantitative conversion of benzyl alcohol) using commercial pure TiO2(P-25). The photocatalytic activity results indicate that designed waste-derived nanomaterials with low TiO2content can efficiently photocatalyze the conversion of benzyl alcohol with relative high selectivity towards benzaldehyde.
