Abstract

In this study, the absorbance of the methyl orange (MO) using TiO2-Al2O3-graphene was synthesized via hydrothermal treatment. The nanocomposite were prepared with different content of TiO2, Al2O3 and graphene. The nanocomposite powder mixture was subjected to hydrothermal treatment at temperature 200°C for 24 h. The morphology, phase identification, crystallite size and functional group were studied using optical microscope, X-ray diffraction and Fourier transform infrared pectrometer. The result showed no new phase formed after hydrothermal synthesized. The nanocomposite of composition 70 wt% TiO2, 20 wt% Al2O3 and 10 wt% graphene showed the lowest crystallite size (26.64 nm). The functional group obtained from the nanocomposite were O-H, N-H and inorganic carbonate group. The composition of without graphene indicate the highest absorbance 32.38% and followed by composition of 50 wt% TiO2, Al2O3 30 wt% and 20 wt% graphene (29.8%) absorbance in visible light.
