CO吸附在经方波电势处理后的纳米结构Pt金属膜电极上可观察到异常红外效应 (AIREs) .在实验基础上用粒子间的相互作用和电子 空穴衰减机理分析、模拟了AIREs ,表明Pt金属表面的纳米岛状结构增强了CO分子间及CO分子与纳米结构表面的相互作用 ,电子 空穴衰减引起的能量转移和粒子间相互作用的增强可以导致异常红外吸收谱线变化特征的出现 .
CO adsorption Abnormal infrared effects (AIREs) were observed on the electrodeposited Pt metal films after square-wave potential treatment.The AIREs were simulated based on the interaction between the particles and the mechanism of electron-hole decay on the basis of experiments The nano-island structure of Pt metal surface enhances the interaction between CO molecules and CO molecules and the surface of nanostructures. The energy transfer caused by electron-hole decay and the enhancement of the interparticle interaction can lead to the appearance of abnormal infrared absorption spectra .
