电极表面的粗糙化处理是进行表面增强拉曼光谱（SERS）研究的重要前提,通过研究两种截然不同的氧化还原循环（ORC）粗糙电极的方法，分析其SERS活性稳定电位区间与ORC还原电位之间的关系，发现高活性的SERS位皆处于亚稳状态，易随电极电位越近零电荷电位（PZC）而发生表面原子重排，以至失去活性．引入强吸附物种，可以使特殊ORC得到的SERS活性在PZC以正电位区稳定存在，并可在PZC以负电位得到常规ORC处理的电极表面上的水的SERS信号，大大拓宽了可进行SERS研究的电位范围．
The roughening of the electrode surface is an important prerequisite for the study of surface enhanced Raman spectroscopy (SERS). By studying two distinct redox cycle (ORC) rough electrodes, the stability potential of SERS activity and ORC reduction potential The results show that the highly active SERS sites are all in a metastable state, and the surface atomic rearrangement tends to occur as the potential of the electrode approaches zero charge potential (PZC), resulting in the loss of activity. The introduction of strongly adsorbed species enables the SERS activity of a particular ORC to be stable in the positive potential region of PZC and to obtain the SERS signal of water on a conventional ORC-treated electrode surface at PZC, greatly widening the possibility of performing SERS studies Of the potential range.
