Co2+ doped Tio2 nanotubes visible light photocatalyst synthesized by hydrothermal method for menthyl orange degradation
Co2+ doped TiO2 nanotubes was successfully synthesized using simple hydrothermal method. The synthesized doped TiO2 nanotubes were characterized by X-ray diffractometer (XRD), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX) and ultra violet diffuse reflectance spec...

description |
Co2+ doped TiO2 nanotubes was
successfully synthesized using simple hydrothermal
method. The synthesized doped TiO2 nanotubes were
characterized by X-ray diffractometer (XRD),
transmission electron microscopy (TEM), energy
dispersive X-ray spectroscopy (EDX) and ultra violet
diffuse reflectance spectroscopy (UV-DRS) for band gap
measurements. XRD pattern shows that after Co ion
doping the phase structure of anatase TiO2 nanotubes
transformed to hexagonal TiO2 with the nanotubes
morphology remained as proved by TEM micrographs.
The band gap energy of Co2+ doped TiO2 nanotubes gave
as low as 2.06 eV compared to undoped TiO2 nanotubes
(3.20 eV). This resulted Co doped TiO2 nanotubes
exhibited higher rate for methyl orange degradation
(MO) than the undoped TiO2 nanotubes. |
