Controllable Synthesis of Modified Porous Anatase TiO₂ with High Photocatalytic Activity.

In this study, we added ZrO₂ and Y₂O₃ to stabilize the anatase TiO₂ phase at higher temperatures. Composite mesoporous TiO₂/ZrO₂/Y₂O₃ (TZY) oxides were prepared by a sol-gel method, and triblockcopolymer P123 and PEG was used as templates. The properties of the synthesized materials were characterized using X-Ray diffraction (XRD), Raman scattering, N₂ adsorption/desorption, and UV-Visible spectrophotometry (UV-Vis) methods et al.
