全反射表面增强红外光谱法的改进及其在表面电化学中的应用
The prerequisite for applying electrochemical ATR-SEIRAS is the appropriate fabrication for nanoparticle film electrodes on IR-transparent windows.For in situ ATR-SEIRAS application，Si is the most frequently used 1R windowto support the working electrodes as compared iv ZnSe arid Ge owing to its stability in acidic electrolytes，as wel1 asreadily available tnaturc and economical wet prac；esses for fabricating various metal electrodes an Si，However. a Siprism per se suffers from strong 1R absorption in the Frequency lower than 1000 cm，preventing the observation of important spectral fingerprints in this region，hence compromises the structural and mechanistic efucidaticm atelectrodes. To overcome this limitation，combining a thin Si wafer with a ZnSe prism far the ATR window may be agood optian.However，this configuraticm requires a critical contras of averali Flatness and local smoothness in orderfor two mechanically polished solid surfaces to be integrated into an optically effcient interface，keeping it from ageneral use in surface and analytical electrochemistry.
