a CORR stability test of Cu2O-pyS. Inset is the schematic illustration showing the flow cell. b Quasi in-situ time-dependent Cu LMM X-ray-excited Auger electron spectra of Cu2O-pyS collected at −0.65 V vs. RHE. Quasi in-situ time-dependent high-resolution N 1s XPS spectra (c), and S 2p XPS spectra (d) collected at −0.65 V vs. RHE. e In-situ ATR-SEIRAS spectra from 1000 cm−1 to 2300 cm−1 recorded over Cu2O-pyS in CO-saturated 0.1 mol/L KOH solution at −0.65 V vs. RHE.
