Abstract

Zn ions surface-doped TiO ₂ nanotubes were synthesized via an assembly process based on ligand exchange reaction and with additional thermal treatment. First the ligand exchange reaction between zinc acetylacetonate and hydroxide radicals on TiO ₂ surface introduced the Zn ions onto the surface of TiO ₂ nanotubes, then the Zn(acac) ₂ assembled TiO ₂ nanotubes were calcined at an optimal temperature (400°C) to eliminate the organic ligands. The as-prepared Zn ions surface-doped TiO ₂ nanotubes showed a further improvement on the photocatalysis activity for degradation of methyl orange in water.
