摘要：
Titanate nanotube thin (TNT) films were synthesised by alkaline hydrothermal method using titanium (Ti) plates as precursors. Copper-cobalt (Cu-Co)-codoped titanate/Ti dioxide (TiO2) nanocomposite thin films were prepared by doping Cu and Co to TNT films through ion exchange method and annealed at 500 degrees C for 120 min. The as-prepared nanocomposite films were characterised by scanning electron microscopy, transmission electron microscopy, X-ray diffractometer, and ultraviolet-visible absorption spectra. The results show that anatase TiO2 particles were grown on the surface of titanate nanomaterial films. The composite materials mainly consisted of anatase TiO2 particles and titanate nanotubes/nanosheets. Cu-Co-codoped titanate/TiO2 nanocomposite thin films exhibited superior visible height adsorption property due to the reduced energy bandgap of composites introduced by additional Cu and Co 3d orbitals.
