采用电位平均表面增强拉曼散射(PASERS)新方法研究二巯基嘧啶(2MP)在不同电极电位下与银电极的作用,PASERS 谱的获得是在快速调制两个电极电位的同时记录 SERS 谱。研究表明2MP在—1.1V 以正的电极电位下,通过硫原子以竖立方式作用于银电极表面,在—1.1V 以负的电位下发生电化学还原反应。
The effect of dimercaptopyrimidine (2MP) on the silver electrode under different electrode potentials was investigated by potentiometric Raman scattering (PASERS). The PASERS spectrum was obtained by rapidly recording the SERS spectra of both electrodes at the same time. Studies have shown that 2MP at -1.1V at a positive electrode potential through sulfur atoms in an upright manner on the silver electrode surface, at -1.1V electrochemical potential reduction occurs under the reaction.
