Fig. 8: Operando electrochemical ATR-IRRAS analysis.
From: Local CO2 reservoir layer promotes rapid and selective electrochemical CO2 reduction
ATR-IRRAS spectra of a Bi-foil, b Bi-UiO-66 and c Bi-UiO-66-CN under electrochemical CO2 reduction conditions (1200−1600 cm−1). d ATR-IRRAS spectrum of Bi-UiO-66-CN in the 2230–2310 cm−1. The ATR-IRRAS spectrum recorded at 0 V was considered as the background and auto-subtracted from all the measurements.
