| Outline of Final Research Achievements |
The hydrothermal reaction of a titanium plate in a mixed aqueous solution of hydrogen peroxide and phosphoric acid under different conditions resulted in the formation of titanium phosphate particles and thin films with various crystal structures and morphologies. Wettability of the titanium phosphate thin films, including superhydrophilicity, superhydrophobicity, and adhesion force between a water droplet and the thin films, could be controlled. A silver nanoparticle/silver titanium phosphate nanobelt thin film showed excellent antibacterial activity against MRSA. The titanium phosphate particles and thin films could be transformed into hierarchical porous TiO2 particles and thin films while keeping their morphologies. The hierarchical porous TiO2 particles showed excellent characteristics of lithium-ion and sodium-ion batteries and removal of organic molecules in aqueous solutions by adsorption and photocatalytic degradation.
