Synthesis and Characterization of Zn/Ni/Fe Magnetic Composite Oxide Nanotubes Assembled in Porous Anodic Alumina

摘要

Zn/Ni/Fe composite oxide nanotubes were synthesized using a 1:2:1 molar precursor solution of Zn(NO₃)₂, Ni(NO₃)₂ and Fe(NO₃)₃ and anodic aluminum oxide as the substrate. The length of the nanotubes is about 1 to 5 ??m, and the outer diameter is 200 nm. The samples were characterized using scanning electron microscope, X-ray diffraction, transmission electron microscope and vibrating sample magnetometer. Magnetization measurement showed the coercivity and largest magnetocrystalline magnetization of Zn/Ni/Fe oxide nanotubes were 60 Oe and 0.6 emu/g. Zn/Ni/Fe oxide nanotubes could be easily prepared using this method, and might be applied as catalysts, magnetic materials or microwave absorbers.View full textDownload full textKeywordsanodic aluminium oxide template, composite oxide, magnetic materials, nanotubesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533174.2010.509709
