Ag Nanorods Coated with Ultrathin TiO(2) Shells as Stable and Recyclable SERS Substrates

TiO(2)-coated Ag nanorods (Ag@TiO(2) NRs) have been fabricated as multifunctional surface-enhanced Raman scattering (SERS) substrates. Uniform TiO(2) shells could sufficiently protect the internal Ag NRs against oxidation and sulfuration, thus the temporal stability of SERS substrates was markedly i...

description TiO(2)-coated Ag nanorods (Ag@TiO(2) NRs) have been fabricated as multifunctional surface-enhanced Raman scattering (SERS) substrates. Uniform TiO(2) shells could sufficiently protect the internal Ag NRs against oxidation and sulfuration, thus the temporal stability of SERS substrates was markedly improved. Meanwhile, due to the synergetic effect between crystalline TiO(2) and Ag, the nanocomposites could clean themselves via photocatalytic degradation of the adsorbed molecules under ultraviolet irradiation and water dilution, making the SERS substrates renewable. Such Ag@TiO(2) NRs were shown to serve as outstanding SERS sensors featuring high sensitivity, superior stability and recyclability.
