| 摘 要： | 在成功地将表面增强拉曼光谱(SERS)拓展到纯锌电极的基础上,利用SERS对4,4'-联吡啶(BiPy)在锌电极表面的作用进行了研究.研究结果表明,BiPy可能是通过N原子垂直或略微倾斜吸附于锌表面,两个吡啶环仍然共面.BiPy和锌电极的相互作用比吡啶分子要强,较大的拉曼散射截面以及两个吡啶环的存在使其可以与锌发生更强的作用.

| Abstract: | In the present paper, surface enhanced Raman spectroscopy (SERS) was employed to study the interaction of 4,4'-bipyridine(BiPy) and Zn electrode. The results indicate that BiPy is adsorced with a vertical (or incline) orientation on the Zn electrode via one N atom of BiPy, and the two pyridine rings still remain on the same plane. BiPy has relatively stronger interaction with zinc metal than pyridine. The larger Raman scattering cross section and the existence of the two pyridine rings make it easy for 4,4'-BiPy to have stronger interaction with zinc metal. |
