Abstract

Mn3O4 nanowires were synthesized by calcination of a precursor obtained in a novel microemulsion. Transmission electron microscopy, X-ray diffraction, infrared spectroscopy, X-ray photoelectron spectroscopy, and selected area electron diffraction were used to characterize the structural features and chemical compositions of the as-synthesized nanowires. The results showed that the as prepared nanowires are composed of tetragonal Mn3O4, the diameters range from 50 to 800 nm, and lengths reach tens of micrometers. The nanowires are highly promising for applications in magnetic materials and sensors.

摘要

通过煅烧在新型微乳液中获得的前驱体合成了四氧化三锰纳米线。利用透射电子显微镜、X射线衍射、红外光谱、X射线光电子能谱和选区电子衍射来表征所合成纳米线的结构特征和化学成分。结果表明，所制备的纳米线由四方相的四氧化三锰组成，直径范围为50至800纳米，长度达到几十微米。这些纳米线在磁性材料和传感器应用方面极具潜力。
