One-dimensional PbTiO3 nanotubes were fabricated via hydrothermal method and the morphology of the nanotube arrays was successfully controlled by adjusting reaction conditions.
One-dimensional PbTiO3 (PTO) nanotubes (NTs) were fabricated via a hydrothermal method based on an anodized TiO2 template. Anatase-structured TiO2 NTs were converted into tetragonal-structured PTO NTs by the entry of Pb2+ ions from high pressure generated during the hydrothermal process. This was confirmed through structural analysis using X-ray diffraction and Raman scattering; increase in the wall thickness of the NTs was observed. However, it was observed that when the conversion process from TiO2 to PTO NTs exceeds the saturation state, the surface morphology of PTO NTs is changed, and PbO particles are formed on the PTO NTs. This constitutes an inhibitory factor in forming PTO NT arrays with clear surface morphology. To prevent this phenomenon, we successfully fabricated PTO NT arrays by controlling the reaction temperature, reaction time, and molar concentration of lead acetate solutions in a hydrothermal process.
