    摘要:

    通過對兩端為Cu（或Ni）導體中間層為高Sn合金的三明治結(jié)構(gòu)線型釬焊接頭試件加載高密度電流，創(chuàng)新性地實現(xiàn)了納米SnO2的快速、便捷制備。經(jīng)SEM、EDX和拉曼光譜分析表征確認所得SnO2為四方金紅石結(jié)構(gòu)，具有多種形貌，如枝狀、針葉狀、草叢狀和棉絮狀。本研究所發(fā)展的制備方法不僅可快速、高效地制備多形貌多尺度SnO2，還可為其它功能金屬氧化物材料的制備提供有效的思路參考和技術(shù)方法借鑒。

    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.
