In situ Raman spectra of a Cu(100) and b Cu(110) electrodes measure in a 0.1 M HClO₄/0.05 M HNO₃ solution during cathodic polarization from 0 to 800 mV vs. Ag/AgCl. c Linear sweep voltammetry of Cu(100), Cu(110), and Cu(111) electrodes in a 0.1 M HClO₄/0.05 M HNO₃ solution during cathodic polarization from 0 to 800 mV vs. Ag/AgCl, reproduced with permission from [50].
