Figure 3. (a) Cyclic voltammograms obtained on platinum-group metal electrodes in 1 mol·L-1 NaOH and 1 mol·L-1 EG[14]. In-situ IRAS of EGOR on PGMs’ electrodes: (b) Pt, (c) Pd, (d) Rh, I Ir. In-situ electrochemical IRAS of EGOR on the (f) Pt and (g) Pd electrodes at 2 mV·s-1, taking the single-beam spectrum at 0 V vs. RHE as the reference spectrum. The potential-dependent band intensity variation of products on (h) Pt and (i) Pd electrodes corresponding to the oltametric scanning; noted that the solid red and blue curves are the CVs of GA oxidation at Pt and Pd, respectively.
