N2 - Green synthesis of gamma alumina (γ-Al2O3) nanoparticles (NPs) with facetted and cubeoctahedral morphologies was undertaken from waste (beverage aluminium cans) via precipitation technique and calcination at the temperature of 1000 oC. The structural properties of γ-Al2O3 were determined with a combination of techniques including BET surface area, field emission scanning electron microscopy (FESEM) with energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM) and x-ray powder diffraction (XRD). XRD analysis confirmed the formation of γ-Al2O3 NPs by comparing with the standard of γ-Al2O3 structure. The BET surface area measured was 129 m2/g. High-resolution transmission electron microscopy (HRTEM) analysis provided evidence of surface-enhanced contrast in facetted γ-Al2O3 NPs structures similar to the commercial γ-Al2O3 NPs.
