Abstract

The effects of tungsten doping on the morphology, stability and photocatalytic activity of TiO₂ nanocrystal colloids were investigated. The nanostructure, chemical state of Ti, W, O, and the properties of tungsten doped TiO₂ samples were investigated carefully by TEM, XRD, XPS, UV-vis, PL and photocatalytic degradation experiments. And the structure-activity relationship was discussed according to the analysis and measurement results. The analysis results reveal that the morphology, zeta potential and photocatalytic activity of TiO₂ nanocrystals can be easily tuned by changing the tungsten doping concentration. The tungsten doped TiO₂ colloid combines the characters of high dispersity and high photocatalytic activity.
