Abstract

A simple and environmentally friendly method to prepare aluminum oxyhydroxide and trihydroxide nanostructures by wet oxidation of AlN/Al composite nanoparticles was developed. The AlN/Al nanoparticles used were produced by electrical explosion of an aluminum wire in nitrogen atmosphere. The obtained nanostructures were characterized employing X-ray diffraction (XRD), transmission and high-resolution scanning electron microscopy (TEM and HRSEM), thermogravimetric analysis (TGA) and N2 adsorption-desorption technique (BET). By changing the wet oxidation conditions, aluminum hydroxides with different phase composition, morphology and texture characteristics were synthesized. After calcination at different temperatures, a range of transition and stable alumina nanostructures were obtained that preserved the morphology of the aluminum hydroxide precursors - agglomerated nanosheets, nanoplates or hexagonal nanorods, up to 1000 °C. Optimal process parameters for maximum surface area development for all the precursor materials have been established.
