In the present study, magnetic Fe3O4 as core with separate two shells, mordenite (MOR) zeolitic shells and CuO shells were post-synthesized. Fe3O4@[email protected] 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@[email protected], CuO, Fe3O4@MOR, Fe3O4@CuO and Fe3O4. The antimicrobial activity of Fe3O4@[email protected] nanocomposite was tested against Escherichia coli, Staphylococcus aureus and core-shell showed bactericidal effect to the antimicrobial properties.

Fe 3 O 4 @ [电子邮件保护的]核壳的制备及其特性,用于研究抗菌性能

在本研究中,以Fe 2 O 4为核心的磁芯,并分别合成了两个壳,丝光沸石(MOR)沸石壳和CuO壳。通过在不同大气中直接煅烧,成功地合成了具有核-壳结构的Fe 3 O 4 @(受电子邮件保护)。通过X射线衍射(XRD),F扫描电子显微镜(SEM),透射电子显微镜(TEM)和振动样品磁强计(VSM)对合成后的纳米复合材料的形貌,结构,磁性和多孔性能进行了表征。根据EDX结果,Fe 3 O 4的重量百分比(wt。%)研究和讨论了铜核,MOR和CuO壳分别为68.13、28.17和3.7%,分别研究了铜离子和MOR沸石对抗菌性能的影响。对Fe 3 O 4 @ [受电子邮件保护],CuO,Fe 3 O 4 @ MOR,Fe 3 O 4 @CuO和Fe 3 O 4进行了比较。测试了Fe 3 O 4 @ [电子邮件保护的]纳米复合材料对大肠杆菌,金黄色葡萄球菌和核壳的抗菌活性。
