Synthesis and Characterization of Composite of Al₂O₃/ Activated Carbon by Hydrothermal Method

Abstract:

Composite of Al₂O₃/activated carbon (Al₂O₃/AC) has been successfully synthesized by hydrothermal method. It was synthesized from activated carbon from oil palm shell waste by mixing with Al₂O₃ powder in ethanol. The mixer was placed in a hydrothermal reactor and heated up to 250°C for 3 hours. Comparison study of surface area between activated carbon and composite of Al₂O₃/AC indicate that surface area decreased from 67.6 to 65.3 m²/g. However, XRD analysis shows that there was a slight different hkl phase. Characterization using FTIR showed that the composite have more oxygen functional groups compared with activated carbon. SEM-EDX of composite of Al₂O₃/AC showed an increasing of crystalline structure on the surface.
