| Summary: | <p>Abstract</p> <p>Single-crystalline nanoporous Nb<sub>2</sub>O<sub>5 </sub>nanotubes were fabricated by a two-step solution route, the growth of uniform single-crystalline Nb<sub>2</sub>O<sub>5 </sub>nanorods and the following ion-assisted selective dissolution along the [001] direction. Nb<sub>2</sub>O<sub>5 </sub>tubular structure was created by preferentially etching (001) crystallographic planes, which has a nearly homogeneous diameter and length. Dense nanopores with the diameters of several nanometers were created on the shell of Nb<sub>2</sub>O<sub>5 </sub>tubular structures, which can also retain the crystallographic orientation of Nb<sub>2</sub>O<sub>5 </sub>precursor nanorods. The present chemical etching strategy is versatile and can be extended to different-sized nanorod precursors. Furthermore, these as-obtained nanorod precursors and nanotube products can also be used as template for the fabrication of 1 D nanostructured niobates, such as LiNbO<sub>3</sub>, NaNbO<sub>3</sub>, and KNbO<sub>3</sub>.</p> |
