| 摘 要： | 金属纳米薄膜的合理制备是衰减全反射表面增强红外光谱法(ATR-SEIRAS)成功应用的关键. 通过简便可控的全湿法镀膜, 即先在红外窗口硅面上化学镀金膜, 而后再电沉积铂或钌, 制得具有极强表面增强红外效应、吸收峰向正常且几乎“无针孔”的铂或钌纳米薄膜电极, 从而可使ATR-SEIRAS技术广泛应用于研究铂、钌电极表面的吸附与反应.

| Abstract: | Economical and practicable all-wet processes have been developed to fabricate virtually pin- hole-free Pt and Ru nanofilms for attenuate-total-reflection (ATR) surface-enhanced IR absorption spec- troscopy (SEIRAS). The processes incorporated an initial chemical deposition of Au nanofilm on the basal plane of a Si prism with a subsequent electrodeposition of desired overlayers. Pt and Ru nanofilms thus ob- tained exhibit unprecedented SEIRA effect with unipolar and normally directed absorption bands for CO adlayers. This versatile strategy opens a wide opportunity for extending ATR-SEIRAS to explore surface adsorption and reaction involved in electrocatalysis. |
