The objective of this research is to synthesis and characterization of graphene oxide (GO)-nano Fe 3 O 4 composite from bagasse. The analysis graphite, GO, and Fe 3 O 4 using XRD result peak at position 2θ 24.56°; 26.61° and 35.4°. GO-nano Fe 3 O 4 composite shows mixture peak of GO and Fe 3 O 4 . When GO was characterized by FTIR, it comes the distinctive vibration bands of-COOH, C = C, C-O, and-CH. While on the composite there are additional bands belonging to Fe-O and Fe-C. The ratio of D band and G band on composite is higher than that of GO, ie 1.45 and 0.79 when characterized used Raman spectroscopy. The morphology structure of the composite when analyzed using FE-SEM-EDX appears to have a large surface area filled with Fe particles on the surface with the largest composition of elements C, O, and Fe. Pore characteristics when determined using SAA belong to mesoporus with surface area total 35.911 m 2 /g and a specific surface area of 42.523 m 2 /g. |
