Synthesis and photocatalytic properties of nanomaterials based on titanium(IV) and zinc(II) oxides

We have synthesized materials based on titanium(IV) and zinc(II) oxides, containing 1 to 60 wt % Zn, at heat-treatment temperatures from 80 to 1150A degrees C, with the formation of multiphase compositions (X-ray amorphous phase, anatase, rutile, ZnTiO3, and/or Zn2TiO4) and studied their phase transitions, morphology, and photocatalytic activity. Increasing the Zn content of the materials is favorable for their spectral sensitization, including the range lambda aeyen 670 nm.
