What is Synthesis of Ruthenium-Doped TiO~2~ Nanotube Arrays for the Photocatalytic Degradation of Terasil Blue Dye about?
The oxidation of terasil blue dye (TB) has been achieved by photocatalysis under UV light using well organized nanotubes of Ti/TiO2 doped with ruthenium (Ru/Ti/TiO2). Ru/Ti/TiO2 were fabricated by Ti anodization followed by impregnation with 0.04, 0.08 and 0.16 wt% of RuCl3 · H2O or KRuO4 as precursor salts. Ti foil anodization was carried out in non-aqueous solutions and in aqueous solutions at pH 7 and pH 12.6. Scanning electron microscopy analyses revealed a morphology of well-defined, organized nanotubes of Ti/TiO2 and Ru/Ti/TiO2. The ruthenium was evenly distributed over Ti/TiO2 surface. Cluster formation was also observed for 0.16 wt% Ru loading. The X-ray diffraction spectra showed anatase and rutile phase in pure Ti/TiO2 and Ru/Ti/TiO2 nanotubes. Therefore, ruthenium doping did not modify the crystalline phase of Ti/TiO2. Raman spectra did not reveal the rutile phase of TiO2 in the composites which is attributed to the laser characteristics used. The optical band gap energies of the Ti/TiO2 and Ru/Ti/TiO2 nanotube arrays showed that ruthenium-doping on Ti/TiO2 had slight effect on the band-gap energy. A decrease in the band gap energy of pure Ti/TiO2 ( 2.88 eV) was observed
