SERS study of the adsorption of benzene on rhodium electrode

Abstract

The Raman spectra of benzene electrochemical adsorption on a roughened Rh electrode have been studied successfully by proper electrode treatment process. The results show that, there is a great difference between the Raman spectra of pure benzene liquid and that of benzene molecule adsorbed on the roughened Rh electrode. It is indicated that the geometry and electron structures have changed greatly after benzene molecule was adsorbed on the roughened Rh electrode. Benzene molecule may be adsorbed on the surface of the roughened Rh electrode with a structure like 1,3-cyclohexadiene. The dependence of benzene electrochemical adsorption on the electrode potential and the electrolyte has been studied in this paper.
