4,4′-联吡啶吸附在银电极上的SERS谱的研究

EXPERIMENTAL STUDY OF SURFACE ENHANCED RAMAN SCATTERING (SERS) SPECTRA OF 4,4'-BIPYRIDINE ADSORBED ON A SILVER ELECTRODE

本文根据0.005mol/L 4,4′-联吡啶/0.010mol/L氯化钾体系的循环伏安曲线、SERS光谱及随外加电位的变化情况,研究4,4′-联吡啶吸附在银电极上的SERS光谱及随外加电位的变化,探讨它们在银电极表面的吸附方式。一、引言自从发现吡啶吸附在银电极表面上产生表面增强喇曼散射(SERS)效应后,这个领域的研究日益深入。1987年。

This paper presents the cyclic voltammetry (CV) curves, surface enhanced Raman scattering (SERS) spectra and potential dependence of 0.005 M 4,4'-bipyridine/0.010 M KCl/Ag electrode system.We studied the SERS spectr of 4,4'-bipyridine adsorbed on a silver electrode, the potential dependence and the molecular adsorption model on a roughened silver electrode surface。
