| 摘 要： | 利用聚偏二氟乙烯(PVDF)热释电膜作为热传感器, 本文首次独立设计了现场光热光谱研究用的电解池, 对电解池的光热信息进行了理论分析, 并用该法研究了碱性溶液中银电极表面氧化层的性质。从光谱的变化证实: Ag表面Ag~2O层的生成与循环伏安曲线上阳极电流增长(约0.22V)同步。类似情况亦发生在AgO层的生成过程。

| Abstract: | The electrochem. cell for in-situ photothermal spectroscopy measurement was designed for the first time independently. A polyvinylidene difluoride (PVDF) pyroelec. film was used as a thermosensor. The photothermal signal in the cell was analyzed theor. The properties of oxide layers formed on Ag surface in alkaline solution have been investigated by using such in-situ spectroelectrochem. method. From the change of spectra it was proved, that the Ag2O layer was formed on Ag surface simultaneously while the anodic current increases on voltammetry curve, as well as in the case for the formation of AgO layer. |
