Surface-Enhanced Raman Spectroscopy in Studies of Corrosion and Inhibition on an Iron Surface

Application and advanced achievement of surface-enhanced Raman spectroscopy (SERS) in corrosion and inhibition on an iron surface have been reviewed. As a technology providing the molecular information of material structure, SERS is widely applied to the studies of metal corrosion and inhibition, especially for iron. Applications of this spectroscopy technology are showed in three aspects: the SERS enhancement theory of Fe surface, the adsorbent mode of inhibitions on Fe surface, and the structure of oxidation or passivation film on a Fe electrode. Furthermore, the tendency of farther study is prospected.
