Fabrication of Silver–Rhodium Nanomaterials for Chemical Sensing Applications
We report a novel class of silver–rhodium (Ag–Rh) nanomaterials that can be used as surface-enhanced Raman scattering (SERS) substrates. Ag–Rh nanomaterials were prepared via the co-reduction of the metal precursors by polyol at elevated temperature. Nanomaterials were characterized by scanning electron microscopy, UV–Visible spectroscopy, and energy-dispersive X-ray analysis (EDS), and they were evaluated for their ability to promote surface-enhanced Raman scattering of a model analyte.
