THE EFFECTS OF THE UNDERPOTENTIAL AND OVERPOTENTIAL DEPOSITION OF LEAD AND THALLIUM ON SILVER ON THE RAMAN-SPECTRA OF ADSORBATES
It is shown that the underpotential deposition (UPD) and dissolution of monolayers of Pb and Tl onto Ag surfaces roughened in a controlled oxidation-reduction cycle produces a Ag surface which shows diminished surface ...
SERS STUDIES ON INTERFACIAL WATER IN CONCENTRATED NACLO4 SOLUTIONS
It has been shown that surface enhanced Raman scattering (SERS) of water can be observed using much lower halide concentrations, from solutions having weak hydrogen bonds between water molecules, such as 8 M NaClO4. The ...
THE INDUCTION OF SERS ON SMOOTH AG BY THE DEPOSITION OF NI AND CO
It is shown that the deposition of foreign metals such as Ni or Co onto smooth Ag substrates induces markedly enhanced Raman scattering from adsorbates at the interface between the foreign metal and the electrolyte.
SURFACE ENHANCED RAMAN SPECTROSCOPIC STUDIES OF ANILINE ON Ag AND Au ELECTRODES
Surface enhanced Raman spectroscopy (SERS) provides a powerful means of obtaining information on adsorbate/surface interactions in view of its unique sensitivity (). With SERS, we started a preliminary study of the ...
AN SERS STUDY OF SILVER ELECTRODEPOSITION FROM THIOUREA AND CYANIDE CONTAINING SOLUTIONS
The electrodeposition of silver from thiourea and cyanide solutions has been investigated using cyclic voltammetry, potential step measurements and ac voltammetry as well as in situ surface Raman spectroscopy (SERS). In ...
RAMAN-SPECTROSCOPY OF ADSORBATES ON THIN-FILM ELECTRODES DEPOSITED ON SILVER SUBSTRATES
Is is shown that enhanced Raman spectra can be detected for CN− absorbed on thin Ni, Co, Cu and Zn layers deposited from cyanide plating baths onto silver substrate electrodes roughened in a preceding controlled ...
