Despite recent research on Cu-based catalysts for the CO2 and CO decrease reactions, surface speciation of the numerous types of Cu surfaces under reaction problems remains an interest of discussion. Herein, in situ surface-enhanced Raman spectroscopy (SERS) is employed to investigate the speciation of four widely used Cu areas, i.e., Cu foil, Cu micro/nanoparticles, electrochemically deposited Cu film, and oxide-derived Cu, at potentials strongly related the CO reduction reaction in an alkali
