In this research, micro/mesoporous boehmite nanostructures were successfully synthesized via hydrothermal route. The size and morphology of boehmite nanostructures could be controlled by adjusting the pH value of the reaction mixture. The resulting products were characterized by X-ray diffraction (XRD), FT-IR, FESEM, TEM analysis. The specific surface area and pore-size distribution of the obtained product as determined by N2 adsorption-desorption measurements show that the boehmite nanostructures possess high porosity properties. Our results showed that the acidic conditions (pH=4, 5) turned out to be favored toward the formation of the nanorods, and the basic conditions (pH=10) toward the formation of the nanoflakes.
