Sažetak
Properties of TiO2 nanostructures have been intensively studied because of the large potential of their possible applications in solar cells, electronics, sensing, photocatalysis as a catalyst support and as new material for mesoporous ion exchange. Titanate nanotubes are particularly interesting because of their large aspect ratio, and large specific surface area, that is beneficial to many TiO2-based devices. In this work we have synthesized hydrogen trititanate (H2Ti3O7) nanotubes by hydrothermal method from TiO2 anatase. We have studied the mechanical stability of synthesized titanate nanotubes to investigate their potential for possible applications or further processing. Raman spectroscopy was used to explore phase transitions caused by high-energy ball milling. Observed phase transitions of titanate nanotubes during milling were compared with the phase transitions of crystalline hydrogen trititanate with the same chemical composition but with different structure and morphology.
