纳米金溶液中表面增强红外研究
Surface-enhanced infrared absorption spectroscopic studies in gold nanoparticles aqueous solution
摘要
Abstract
Surface-enhanced infrared absorption (SEIRA)has been extensively applied to in situ monitoring of adsorption and electrochemical process at the interface by using attenuated total reflection (ATR)configuration.In this paper,the authors reported a surface-enhanced infrared spectroscopy electrochemical techniques based on external reflection.They used gold nanoparticles (GNPs)as the reaction environment and the positive charging dopamine (DA)and [Co(phen)3 ]3+ as the reactant.Experimental results showed that SEIRA could be observed in GNP dispersed solution by using infrared reflection absorption spectroscopy (IR-RAS).This phenomenon was owing to electrostatic interactions,the positive charging dopamine and [Co(phen)3 ]3+ could be absorbed on negatively charged GNP,so SEIRA could be clearly observed due to the adsorbed molecular.关键词
