【摘要】 <正>缓蚀剂的研究和开发一直是个相当活跃的领域,利用SERS效应与电化学技术相结合可以探讨各种不同的有机分子对金属的缓蚀作用.本文选用苯骈咪唑烯丙基硫醚（BMAT）、苯骈咪唑炔丙基硫醚（BMPT）和二巯基苯骈咪唑（MBI）三种缓蚀剂研究它们在银电极和不锈钢f银)电极上的吸附行为。比较BMAT,BMPT和BMI固体的拉曼谱图（图1）和它们在银电极上的SERS谱图（图2）可知,它们存在较大的差异:例如,在固体谱中没有1180cm^-1的谱峰,而在银电极上该谱峰是最强的,并且更多还原

【Abstract】 Surface enhanced Raman spectroscopy(SERS) has been applied to study BMAT,BMPT and MBI adsorbed on silver electrodes.Their SERS spectra are very similar, indicating that they all interact with silver via the nitrogen atom rather than sulphur atom.Raman microscopy has also been used to study the SERS of BMAT adsorbed on stainless steel covered partially by silver mieroislands.The SERS spectra are different significantly from that on pure Ag electrodes.更多还原
