6/1/2020, · The elemental mapping of CuFe 2 O 4 @RSDBC was further confirmed by the EDX analysis. Figure 2 showed obvious elements of cooper, iron, oxygen, silicon and aluminum, all of which are typical elemental composition of CuFe 2 O 4 @RSDBC. This may indicate that the CuFe 2 O 4 was successfully loaded on RSDBC.
