In this paper, a brief description of the rhodium electrode surface enhanced Raman spectroscopy (SERS) method with a strong activity of the rhodium electrode can be applied by the square wave current constant current coarse access to the model molecule pyridine surface pull Man spectroscopic studies show that the electrode has good stability and reversibility, and the surface enhancement factor of up to 400. In the rhodium electrode on carbon monoxide oxidation process Raman spectroscopy simultaneously detected bridge And Raman signals vibrating linearly adsorbed on CO and Pt C. The present study shows that rhodium can be used as a versatile SERS substrate and Raman spectroscopy can be used as a universal tool for interfacial research.
