We have observed similar surface color changes of glassy carbon (GC) after anodic "electrodeposition" with the same electrolytes in the presence or the absence of silanes, indicating that sample color changes can arise from more than one thing and thus should not be used as the sole indicator of silica film formation. Nevertheless, the formation of silicate films during anodic electrodeposition is verified by X-ray photoelectron spectroscopy (XPS) measurements.
我们观察到，在有无硅烷存在的情况下，使用相同电解质进行阳极“电沉积”后，玻璃碳（GC）会出现类似的表面颜色变化，这表明样品颜色变化可能由多种因素引起，因此不应将其作为二氧化硅膜形成的唯一指标。尽管如此，通过X射线光电子能谱（XPS）测量证实了阳极电沉积过程中硅酸盐膜的形成。
