摘要：

Raman Spectroscopy is a powerful technique in characterizing the surface structure at the molecular level. Rh, due to its special application as catalysts in the catalytic and electrochemical reaction, has been one of the most important materials in surface sciences. However, Rh surface has not been considered as an appropriate substrate for generating prominent SERS effect. Furthermore, it was found very difficult to be roughened since it will grow naturally in air an oxide layer to retard the further formation of the surface oxide and it is very easy to form various forms of rhodium oxides as indicated in the phase diagram of Rh[1]. To select a method to roughen the surface and to extend SERS to Rh seem not an easy task.
