8271 1257 Fe3O4 NPs 23 3.7 nm TEM The Fe3O4 nanoparticles were synthesis by the co-precipitation method, and they were around 23 ± 3.7 nm in size as measured by TEM (Figure S2).
8356 1349 Fe3O4 NPs 9 1 nm TEM The pristine Fe3O4 NPs exhibit a spherical shape with a uniform diameter in the range of 8–10 nm.
8425 1418 Fe3O4 NPs 200 nm TEM average diameter
8430 1423 Fe3O4 NPs 12 nm TEM As shown in Fig. 1(b), irregular Fe3O4 NPs with an average size of 12 nm were observed. For Fe3O4@GO MNCs shown in Fig. 1(c), a large amount of Fe3O4 NPs were observed on sheet like GO. TEM images confirmed the successful assembly of Fe3O4 onto GO to form Fe3O4@GO MNCs.
