7466 175 Fe3O4/CoFe-LDH 320-350 nm TEM As displayed in Fig. 2a and b, Fe3O4 were well-separated lycheelike spherical structure with mean grain size of about 300 nm. Fig. 2c-e clearly show the core-shell structure where Fe3O4 microspheres were encapsulated in CoFe-LDH nanosheets. Since there were no obvious boundaries between the core and shell, we approximately estimated that the particle sizes of Fe3O4/CoFe-LDH were in the range of 320-350 nm 44.5
