非水体系中哌啶在银电极表面的表面增强喇曼散射

The surface enhanced Raman scattering of piperidine adsorbed on silver electrode surface in nonaqueous media

本文测定了哌啶在甲醇溶液中吸附在银电极表面的表面增强喇曼散射(SERS)光谱,及其随电位的变化,同时还测定了电极经不同氧化-还原循环(ORC)预处理时的SERS谱,对所得结果进行了分析比较,并进一步研究了非水体系和水体系SERS谱之间的关系.实验结果表明:哌啶在甲醇体系中比在水体系中SERS谱的增强因子要小,并且它们的SERS谱线随电位的变化也有一定的差别.

This paper presents a study of surface enhanced Eaman scattering (SEES) spectra of piperidine adsorbed on a silver electrode surface in the methanol solution. The potential dependence of the SEES spectra and SEES spectra of piperidine during two kinds of the Oxidation-reduction cyclic pretreatment of the silver electrode are measured. We have studied the relationship of SEES of piperidine in the methanol and aqueous system. The experiments show that the enhancement factor of SEES of piperidine in methanol system is smaller than that in the aqueous system and their potential dependence is different.
