Malaysian Journal of Analytical Sciences, Vol 20 No 1 (2016): 149 - 156 X-Ray Diffraction (XRD) XRD analysis was used to further confirm and compare the crystalline structure and composition of the obtained hybrid nanomaterials. XRD patterns of graphite, graphene oxide (GO) and hybrid materials synthesized at different weight loading ratios are shown in Figure 3. Graphite shows a very sharp diffraction peak at 2θ = 26.5o which corresponds to d-spacing of 0.34 nm with an index (002). Meanwhile, GO exhibits typical diffraction peaks centered at 2θ = 11.5o (001) corresponding to interlayer distance of ~ 0.77 nm and 2θ = 22.3o (100) which is consistent with the previous report [14]. The diffraction peak appears from GO is originated from (002) layer plane from graphite. The interlayer d-spacing of graphene oxide (0.77 nm) tends to be much larger than graphite (0.34 nm) due to the presence of many oxygen functionalities that attached to the surfaces of GO with some potential defects related to the strong oxidation process. A broad diffraction peak appears at 2θ ≈ 22.3o due to the short range order of stacked graphene sheets. (e) (d) )u.a(ytisnetnI (c) (b) (a) 20 40 60 80 2 Theta Figure 3. XRD patterns of (a) graphite, (b) GO, (c) Fe/RGO 1:1, (d) Fe/RGO 1:4, and (e) Fe/RGO 2.5:1 The XRD patterns of Fe/RGO nanocomposite with ratio of 1:1 and 1:4 are very similar. Both Fe/RGO 1:1 and Fe/RGO 1:4 showed the most intense diffraction peaks at 2θ ≈ 24o and 23o respectively corresponding to the peak resulted from GO. However, both Fe/RGO 1:1 and Fe/RGO 1:4 do not show any peak that is corresponding to the magnetite compound. The Fe/RGO 1:1 is less likely to show magnetic properties due to the presence of minute amount of Fe2O3 particles in their composite. There are some diffraction peaks that are indexed to Fe3O4 particles in 153PDF Image | GRAPHENE-BASED MAGNETIC HYBRID NANOCOMPOSITE
