铑电极上的表面增强拉曼光谱研究
Rhodium as a Ubiquitous Substrate for Surface Enhanced Raman Spectroscopy
摘要
Abstract
Raman Spectroscopy is a powerful technique in characterizing the molecular structure at the molecular level. However, only after the discovery of surface enhanced Raman scattering (SERS) effect, has it become one of the most widely used technique in surface sciences. The limitation that only Ag, Au and Cu can produce prominent SERS signal of practical significance, greatly hinders the application of this technique. Recently our group has made great progress in extending SERS to pure transition metal surfaces, such as Pt, Ni, Fe, Co etc［1］. Rh, due to its special application as catalysts in the catalytic or electrochemical reaction has made it one of the most important materials in surface sciences. It will be of great help for understanding the interfacial phenomenon and possibly the SERS mechanisms if we can extend SERS to the Rh surface. However, It has been found that, Rh is very difficult to be roughened since it will grow naturally in air an oxide layer which will retard the further formation of surface oxides. Furthermore, Rh is very easily oxidized to various forms of rhodium oxides as can be found from the phase diagram of Rh［2］. How to select a method to roughen the surface and to extend SERS to Rh seems not an easy task.关键词
