Formation than that using the polymeric precursor, PEI. Lastly, multilayered core hell Fe3 O4 -SnO2 -C nanoparticles were synthesized by the amino functionalization on the Fe3 O4 -SnO2 particles via APTES. Figure 8a shows the XRD pattern in the Fe3 O4 -SnO2 -C composite nanoparticles. The nanoparticles GYKI 52466 Membrane Transporter/Ion Channel showed peaks of Fe3 O4 and SnO2 corresponding towards the (110), (101), (200), (211), (220), (202), (220), (311), (400), (422), (511), and (440) planes. Furthermore, the low11 of 15 intensity peak at two = 22.1 corresponds to the (002) plane of carbon, which originated from the carbon layer formed by the carbonization of glucose [37].Figure 8. XRD patterns (a) and Raman spectra (b) on the Fe33O4 -SnO2-C composite nanoparticles. Figure eight. XRD patterns (a) and Raman spectra (b) of the Fe 4 two -C composite nanoparticles.As shown in Figure 8b, the Raman spectrum the Fe O three -SnO2 -C composite nanoparAs shown in Figure 8b, the Raman spectrum of from the 3Fe4O4-SnO2-C composite nanoticles confirmed the formation of carbon on their surface. Two powerful sturdy characteristic particles confirmed the formation of carbon on their surface. Two characteristic carbon -1 peaks peaks have been observed more than the wavenumber selection of 1000800 cm-1. In general, carbonwere observed over the wavenumber range of 1000800 cm . In general, the D band, which appears only only disordered or finite-sized graphite crystals are present, will be the D band, which appearswhen when disordered or finite-sized graphite crystals are prenot identified in well-crystallized graphite [38]. The D band at 1371 cm-1 indicates the pressent, isn’t identified in well-crystallized graphite [38]. The D band at 1371 cm-1 indicates ence of sp3 defects within the carbon carbon network, whereas the at 1584 cm-1 corresponds the presence of sp3 defects in the network, whereas the G band G band at 1584 cm-1 correto the Eto the E2g stretching vibration of graphite 2 electronic configuration. sponds 2g stretching vibration of graphite with spwith sp2 electronic configuration. The intensity ratio in the D- and G-bands (I /IG offers helpful information about The intensity ratio on the D- and G-bands (IDD/IG)) provides valuable information regarding the crystallinity of carbon material. The closer the ID/IG/IG value zero, the the higher is crystallinity of carbon material. The closer the ID worth to to zero, FM4-64 site greater will be the the the degree of structural alignment in the formed carbon material The D/IG ratio ratio degree of structural alignment on the formed carbon material [39]. [39]. IThe ID /IGof the from the Fe3 O4 -SnO2 -C composite nanoparticles was roughly 0.5706, as determined Fe3O4-SnO2-C composite nanoparticles was approximately 0.5706, as determined using employing Lorentz fitting. This indicates that the formed carbon layer had a relatively ordered Lorentz fitting. This indicates that the formed carbon layer had a fairly ordered structure. structure. Even so, this carbon layer is usually regarded amorphous carbon as a result of Nevertheless, this carbon layer might be regarded as amorphous carbon because of its high ID its higher ID value. As a result, the layer formed around the surface with the Fe O4 -SnO2 nanoparticles worth. As a result, the layer formed on the surface in the Fe3O4-SnO2 3nanoparticles was conwas confirmed to be amorphous graphitized carbon, which was formed when the sulfuric firmed to become amorphous graphitized carbon, which was formed when the sulfuric acid acid made use of in the coating method promoted the dehydration reaction of the olig.
