Surface-enhanced Raman scattering (SERS) integrates high levels of sensitivity and spectroscopic precision with tremendous potential for chemical and biomolecular sensing. On the other hand, metal nanoparticles have been employed in catalysis with great promise for future energy technologies. Interactions between oxygen and gold surfaces are of fundamental importance in catalysis and other multiple and diverse areas of science and technology. We propose to synergistically integrate the two aspects of metal nanoparticles in dual-functional Ag@Au core-shell nanostructures to take advantage of high SERS enhancement factor of Ag and unique catalytic property of Au. Pure Au nanoparticles with specific size are also prepared to be a comparison with Ag@Au core-shell structures in terms of SERS enhancement and catalytic properties by in situ Raman detection during the decomposition of hydrogen peroxide.
