In this study, for the first time, we investigated the influence of Sn foil purity and electropolishing pretreatment procedure on the growth of nanoporous SnO fabricated during galvanostatic anodization. For this reason, anodic tin oxide layers were fabricated on different Sn foil substrates in a time range from 5 to 90 min, and a detailed inspection of morphological features of as-grown films was carried out using scanning electron microscope (SEM) and Atomic force microscope (AFM) microscopy. Afterward, a comparative investigation of optical and photoelectrochemical properties depending on the time of anodization and the substrate type was elucidated and discussed. The findings of the study indicate that the type of substrate influences the morphology and properties of the material, with the effect becoming more pronounced as the thickness of SnO increases.
在本研究中，我们首次研究了锡箔纯度和电解抛光预处理程序对恒电流阳极氧化过程中制备的纳米多孔SnO生长的影响。因此，在不同的锡箔基板上，在5至90分钟的时间范围内制备了阳极氧化锡层，并使用扫描电子显微镜（SEM）和原子力显微镜（AFM）对生长薄膜的形态特征进行了详细检查。之后，阐明并讨论了根据阳极氧化时间和基板类型对光学和光电化学性质的对比研究。研究结果表明，基板类型会影响材料的形态和性质，随着SnO厚度的增加，这种影响会变得更加明显。
