Abstract
Cobalt decorated titanium dioxide nanotubes were synthesized by electrodeposition method. X-Ray diffraction (XRD) results showed that Co-TiO2 nanotubes only include anatase phase. The framework substitution of Co in TiO2 nanotubes were established by Field Emission Scanning Electron Microscope (FESEM), Raman Spectroscopy, X-ray Diffraction (XRD) and the photocatalytic properties is tested by UV lamp chamber. The increase of cobalt concentration enhanced degradation of methyl orange (MO) in the UV-Vis absorption spectra. The Co suppressed the growth of TiO2 grains, agglomerates them and shifts the band absorption of TiO2 from ultraviolet (UV) to visible region. The photocatalytic activity of samples were tested for degradation of methyl orange (MO) solutions. The presence of 0.05 mM of cobalt chloride concentration in TiO2 resulted in a catalyst with the highest activity under visible irradiation.
