Synthesis of α-Al2O3 nanosize by combustion reaction using sucrose and graphene oxide as fuel precursors

Abstract

The α-Al₂O₃ nano-sized particles were generated employing a combustion reaction using sucrose and graphene oxide as fuel precursors. The synthesized α-Al₂O₃ material was analyzed using scanning electron microscopy (SEM), brunauer-emmett-teller (BET), X-ray diffraction (XRD), dynamic light scattering (DLS), and high-resolution transmission electron microscopy (TEM) techniques. XRD study identified α-Al₂O₃ nanocrystals from aluminum oxide. The results of the SEM and TEM investigations demonstrated that the sucrose samples had particle sizes in the nanoscale range. The study found that higher sucrose concentrations resulted in smaller α-Al₂O₃ particles. The α-Al₂O₃ nano-powder had an average diameter of less than 30 nm. Sucrose and GO were coupled for the first time to fabricate nanosized α-Al₂O₃ powders. The findings may pave the way for new methods of producing stable aluminum nanoparticles in α-phase, which might be useful in a variety of applications.
