Porous zinc ferrite (ZnFe(2)O(4)) nanorods with a diameter of around 50 nm and a length of several micrometers have been synthesized by a microemulsion-based method in combination with calcination at 500 °C. The morphology and structure of the ZnFe(2)O(4) nanorods and its precursor (ZnFe(2)(C(2)O(4))(3) nanorods) were systematically characterized by x-ray powder diffraction, transmission electron microscopy, field emission scanning electron microscopy and high-resolution transmission electron microscopy. The formation mechanism for the porous ZnFe(2)O(4) nanorods is also discussed. Moreover, the porous ZnFe(2)O(4) nanorods were applied in a room-temperature ethanol sensor and exhibited much better sensing performance than ZnFe(2)O(4) nanoparticles.
采用基于微乳液的方法并结合在500°C下煅烧，合成了直径约50纳米、长度为几微米的多孔铁酸锌（ZnFe₂O₄）纳米棒。通过X射线粉末衍射、透射电子显微镜、场发射扫描电子显微镜和高分辨率透射电子显微镜对ZnFe₂O₄纳米棒及其前驱体（ZnFe₂(C₂O₄)₃纳米棒）的形貌和结构进行了系统表征。还讨论了多孔ZnFe₂O₄纳米棒的形成机理。此外，将多孔ZnFe₂O₄纳米棒应用于室温乙醇传感器，其传感性能比ZnFe₂O₄纳米颗粒好得多。
