Figure 7. (A and C) HY-Cu2O (100) and (B and D) Cu2O (100) under different applied potentials: (A and B) CO2 atmosphere; (C and D) Ar atmosphere. All spectra were recorded over 4,000 cm-1 to 2,500 cm-1 using in situ ATR-SEIRAS. ATR-SEIRAS: Attenuated total reflection surface-enhanced infrared absorption spectroscopy.
