本文通过测定邻菲啰啉分子(O-Phen)吸附在银电极表面的表面增强喇曼散射(SERS)光谱及不同支持电解质对邻菲啰啉分子吸附在银电极表面的SERS光谱的影响,探讨了邻菲啰啉分子在银电极表面的吸附方式和不同支持电解质在银电极表面的吸附能力。实验结果表明:O-Phen通过两个氮原子竖直吸附在银电极表面,不同支持电解质在银电极表面的吸附能力不同,且对邻菲啰啉分子的SERS效应的影响也不同。
In this paper, the effect of surface enhanced Raman scattering (SERS) spectra of orthophenylene oxide (O-Phen) adsorbed on the silver electrode surface and the SERS spectra of different supported electrolytes adsorbed onto the surface of silver electrode by orthophenanthroline molecules The adsorption of phenanthroline molecules on the silver electrode surface and the adsorption capacity of different supporting electrolytes on the surface of silver electrode were investigated. The experimental results show that O-Phen adsorbs vertically on the surface of silver electrode through two nitrogen atoms. The adsorption capacities of different supporting electrolytes on the surface of silver electrode are different, and the influence of SERS on the phenanthroline molecules is also different.
