系统地研究了玻璃上铟锡氧化物（ITO）的电化学还原。揭示了ITO的吸光度和电阻随着还原而增加。扫描电子显微镜（SEM）图像显示，集成的ITO膜在施加负电势时会溶解并形成颗粒。颗粒由金属In和Sn组成，其特征在于X射线衍射（XRD）和X射线光电子能谱（XPS）。ITO的还原在很大程度上取决于电解质的条件，主要是pH和阴离子。发现开始电位随着电解质的pH增加而向负移动。NO 3 -离子被发现显著抑制ITO的减少，通过移动还原电位负约 与SO相比为500 mV4 2-，氯-和Br - 。它也可以作为抑制剂通过非常低的浓度加入到氯- -dominant电解质。此外，发现电化学还原的ITO表现出优异的非线性光学性能，其透射率可通过还原电位和时间来调节。这表明ITO的电化学还原有希望的有用应用。

The electrochemical reduction of indium tin oxide (ITO) on glass is systematically studied. It is revealed that the light absorbance and electric resistance of ITO increases upon reduction. Scanning electron microscopy (SEM) images show that the integrate ITO films dissolve and form particles upon applying negative potentials. The particles consist of metallic In and Sn, as characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The reduction of ITO strongly depends on the electrolyte conditions, mainly pH and anions. The onset potential is found to shift negative as the pH of the electrolyte increases. NO3− ions are found to significantly inhibit the reduction of ITO, shifting the reduction potential negative by ca. 500 mV as compared with SO42−, Cl− and Br−. It can also serve as inhibitor by adding very low concentration to the Cl−-dominant electrolyte. Moreover, it is found that the electrochemically reduced ITO show excellent non-linear optical performance, with transmittance tuneable by reduction potential and time. This suggests a promising useful application of the electrochemical reduction of ITO.
