 In this study the efficiency of different bare, doped and composite photocatalysts were compared, under UV and visible light irradiation in order to show a detailed picture of the relative performance of the best photocatalysts developed in our laboratories and the mostly investigated reference titanias. The syntheses of our photocatalysts were optimized in order to achieve maximum photocatalytic activity under UV and visible light irradiation. Non doped commercial (Aeroxide P25, Aldrich a...

 BiOCl/BiOBr uniform flower-like composite photocatalysts had been successfully synthesized through a one-pot ethylene glycol (EG)-assisted solvothermal process in the presence of 1-hexadecyl-3-methylimidazolium chloride ([C16mim]Cl) and 1-hexadecyl-3-methylimidazolium bromide ([C16mim]Br) reactable ionic liquids. Their structures, morphology, and optical properties were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), ene...

 A facile method to prepare metallic platinum doped ordered mesoporous titania–silica materials (Pt–TiO2/SiO2) was demonstrated by using P123 as the soft template. The materials exhibited anatase and rutile biphase with the ratio of 63:37; meanwhile, they possessed 2D hexagonal p6mm structure with large pore size and high surface area. Pt–TiO2/SiO2 materials were used as efficient photocatalysts to degrade two aqueous light insensitive compounds, p-nitr...
