Zinc ions surface-doped titanium dioxide nanotubes and its photocatalysis activity for degradation of methyl orange in water

Zn ions surface-doped TiO2 nanotubes were synthesized via an assembly process based on ligand exchange reaction and with additional thermal treatment. The as-prepared Zn ions surface-doped TiO2 nanotubes showed a further improvement on the photocatalysis activity for degradation of methyl orange in water.
