Ethanol electro-oxidation over Pt(hkl): Comparative study on the reaction intermediates probed by FTIR and SFG spectroscopies

Résumé

We have investigated the adsorbed intermediates of ethanol electro-oxidation at Pt(1 1 1), Pt(1 0 0) and Pt(1 1 0) using FTIR and SFG spectro-scopies. Mainly, we focus on the CO formation. The aim of the present work is to compare the responses coming from two different surface probes: FTIR spectroscopy and SFG spectroscopy. Between 1800 cm −1 and 2300 cm −1 , our FTIR and SFG results are in good agreement. Specifically in the case of the ethanol/Pt(1 1 1) interface, the SFG spectroscopy presents higher sensibility to the interface response compared to the FTIR spectroscopy.
