摘要：

Rough Cu surfaces, with pattern formation, were obtained by a nonequilibrium electrodeposition from acidic electrolyte. Wavelength dispersive spectrometer (WDS)/energy-dispersive spectrometer (EDS) investigations revealed that such surfaces are highly oxidized. Surface enhanced Raman scattering (SERS) investigations confirmed a complex structure and composition of such a substrate; a distinct difference in spectral characteristics of an adsorbate on Cu2O, pure metallic Cu clusters, and some other, not yet well characterized, metallic Cu clusters, which predominate on the copper surfaces activated by standard electrochemical methods, were identified and distinguished.
