Abstract: The surface enhanced Raman scattering(SERS) technique has been used to investigatethe oxidation and the anti-oxidation effect of azole compounds for metallic copper in air.Benzotriazole(BTAH) and 2-mercaptobenzimidazole(MBIH) were found to be adsorbed oncopper surface, showing a strong antioxidation ability for copper, while benzimidazole(BIMH) failed to protect copper from oxidation.When the copper surface had covered by Cu2O molecules in thickness of 1~2 layers, and adsorbed MBIH, it showed much lowerantioxidant activity.

Key words: surface-enhanced Raman scattering, copper, oxidation, antioxidation, azole
