a, b Operando DB-FTIR spectroscopy with formic acid adsorbed on the mono- and bimetallic catalysts at elevated temperatures from room temperature to 473 K (1 → 11, as indicated by the arrows). The typical absorption bands were indicated by the dashed lines. Normalized intensities of c 1595 cm−1, and d 1718 cm−1 bands as a function of the temperature; all the spectra were referred to those collected at room temperature.
