| 摘 要： | 单质锡箔片在草酸溶液中利用电化学阳极氧化合成出前聚体, 并将前聚体通过加热氧化制备出具有纳米级孔道的二氧化锡材料. 电化学氧化制备的氧化亚锡纳米孔径和分布随外加电压、电解质溶液浓度和氧化时间而变化. 经场发射扫描电镜(FE-SEM)、X射线衍射(XRD)和孔径分析仪(Poresizer)分析显示, 阳极氧化的前聚体是氧化亚锡, 通过在空气中加热转化为二氧化锡, 在详细研究制备条件和氧化锡孔道形貌的基础上, 提出了氧化锡纳米孔的生成机理符合氧化溶解理论模型.

| Abstract: | The formation of tin dioxide nanotubes on tin substrates anodizing in oxalic acid electrolytes and annealing in the air was investigated. Under optimized electrolyte, oxidation and anneal conditions, nanotubes of tin dioxide were fabricated. Topologies of the anodized tin change remarkably along with applied voltages, electrolyte concentration and oxidation time. Field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD) and poresizer indicate the nanotubes are formed due to the competition of tin monoxide formation and dissolution under the assistance of electric field. The formation mechanism of nanotubes agrees with the theoretic model of oxidation-dissolution. |
