摘要

We report here the first electrochemical oxidation-reduction cycle procedure to roughen gold substrates in 0.1 N HCl aqueous solution containing 1 mM rutile TiO2 nanoparticles under the irradiation of UV light. It is encouraging to find that the oxidized peak in the anodic scan, which is responsible for the surface-enhanced
Raman scattering, increases significantly due to the effect of adding TiO2 under an electric field and UV irradiation. Moreover, the SERS spectrum of polypyrrole electrodeposited on the corresponding roughened gold substrate exhibits a 5-fold higher intensity compared to that without the contribution of TiO2 nanoparticles.
