Boehmite [AlOOH] nanoneedles, nanorods, and nanotubes were successfully synthesized by a facile sol‐hydrothermal method without using any surfactant. Calcination of the corresponding boehmite nanostructures at 700 °C gave the corresponding γ‐Al~2~O~3~ nanoneedles, nanorods, and nanotubes. The resulting products were characterized by XRD, TEM, HRTEM, and FT‐IR spectroscopy. We found that the conditions used to produce the sol and the pH value of the hydrothermal process have important effects on the nucleation and growth of nanostructured materials.
