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...
