Abstract

In comparison with the hybridization with 0D TiO₂ nanoparticle, 2D layered TiO₂ nanosheets are much more effective in the improvement of the photocatalytic activity and photostability of semiconducting compounds. The 2D TiO₂-Ag₃PO₄ nanohybrid described in this paper shows a greater decrease in the electron-hole recombination upon hybridization and a stronger chemical interaction between the components than the 0D homologue. This result confirms the benefits of 2D layered TiO ₂ nanosheets as a building block for efficient hybrid-type photocatalyst materials.
