Abstract
Synthesis and characterization of γ-boehmite and γ-alumina nanoparticles with a platelet shape are described.
First an environmentally friendly hydrothermal synthesis method is applied to form nanostructured γ-boehmite, starting from the hydrolysis of aluminium alkoxide. Subsequently γ-alumina nanopowder is obtained after calcination of the γ-boehmite at 600 °C.
Transmission electron microscopy (TEM) reveals that the particle size of γ-AlOOH and γ-Al2O3 lies between 30 and 80 nm. Furthermore, the nanopowders have been characterized by photon correlation spectroscopy (PCS) and X-ray diffractometry (XRD).
