Facile one-pot fabrication and high photocatalytic performance of vanadium doped TiO2-based nanosheets for visible-light-driven degradation of RhB or Cr(VI)

- V-TNSs with high stability and recyclable usability were prepared by one-pot method.
- Vanadium doping results in the changes in the structure, vacancy and red shift range.
- Vanadium doping leads to obviously increase of the Ti3+ ions content.
- Doped vanadium can effectively trap electrons to enhance the separation of charges.
- V-TNSs exhibit excellent visible-light photoactivity for RhB solution or Cr(VI).
