Abstract
In the present study, magnetic Fe3O4 as core with separate two shells, mordenite (MOR) zeolitic shells and CuO shells were post-synthesized. Fe3O4@MOR@CuO with a core-shell structure has been successfully synthesized through direct calcinations in different atmosphere air. The morphology, structure, magnetic and porous properties of the post-synthesized nanocomposite were characterized by using X-ray diffraction (XRD), F scanning electron microscope (SEM), transmission electron microscopy (TEM), and vibration sample magnetometer (VSM). Based on EDX results, the weight percentage (wt.%) of Fe3O4 cores, MOR and CuO shells were calculated 68.13, 28.17 and 3.7%, respectively the influences of cupric ion and MOR zeolite for antimicrobial properties investigated and discussed. A comparison was made between the Fe3O4@MOR@CuO, CuO, Fe3O4@MOR, Fe3O4@CuO and Fe3O4. The antimicrobial activity of Fe3O4@MOR@CuO nanocomposite was tested against Escherichia coli, Staphylococcus aureus and core-shell showed bactericidal effect to the antimicrobial properties.
