Abstract—Ce-doped TiO2-multi walled carbon nanotubes (Ce- In this paper, multi walled carbon nanotubes/TiO2
doped MCNTs/TiO2) composites were essfully synthesized (MCNTs/TiO2) composites were prepared by the hydrothermal

morphology and optical properties of samples were characterized performance. The as-synthesized samples were characterized
using X-ray diffraction (XRD), transmission electron microscope by X-ray diffraction (XRD), transmission electron microscope
