Oxidation And Corrosion

Ag–Ti alloy nanorods are designed and fabricated. Taking advantage of the higher chemical activity of Ti compared with Ag, Ti can be sacrificed against oxidation and corrosion, protecting Ag in harsh environments, further ensuring long-term stability of the SERS substrates.
