| 摘 要： | 通过对两端为Cu（或Ni）导体中间层为高Sn合金的三明治结构线型钎焊接头试件加载高密度电流，创新性地实现了纳米SnO2的快速、便捷制备。经SEM、EDX和拉曼光谱分析表征确认所得SnO2为四方金红石结构，具有多种形貌，如枝状、针叶状、草丛状和棉絮状。本研究所发展的制备方法不仅可快速、高效地制备多形貌多尺度SnO2，还可为其它功能金属氧化物材料的制备提供有效的思路参考和技术方法借鉴。

| Abstract: | Nano tin oxide (SnO2) was synthesized by a novel, fast and facile approach through applying electric current of high density to a line-type joint specimen consisting of a high tin-content alloy between two pieces of conductor (copper or nickel). The fabricated SnO2 shows various morphologies, such as branch-like, pine-leaf-like, grass-like and batting-like, and has the tetragonal rutile structure confirmed by scanning electron microscopy, energy dispersive X-ray spectroscope and Raman spectrum. The present work has not only offered a facile and novel method for fabricating SnO2 of various morphologies, but also provided an inspiriting yet practical idea as well as technical possibilities for preparation of other functional oxide materials. |
