The CO tolerance of Pt nanoparticles in PtAuSn/W 2C is improved by the presence of oxide species on W 2C through a bifunctional mechanism, as well as the electronic charge transfer from the W 2C support to the metallic nanoparticles through an electronic effect. FTIR spectra analysis and EC-MS during the ethanol oxidation reaction (EOR) show C–C bond breaking at the admission potential (0.05 V RHE) and an onset potential for the CO 2 formation at E ≥ 0.20 V RHE. We show that PtAuSn/W 2C has a higher electrocatalytic performance than PtAuSn/C, with a CO 2 conversion efficiency of 6.5% detected at 0.65 V versus the reversible hydrogen electrode (RHE) at room temperature with on-line quantitative EC-MS measurements. For a better understanding of the reaction mechanism, in situ techniques such as electrochemical mass spectrometry (EC-MS) and Fourier transform infrared spectroscopy (FTIRS) are employed. Vulcan XC-72-supported Pt(3 wt %)Au(3 wt %)Sn(10 wt %) is used as a reference (PtAuSn/C). The electrocatalytic behavior of a tungsten carbide-supported Pt(3 wt %)Au(3 wt %)Sn(10 wt %) catalyst (PtAuSn/W 2C) is investigated toward the oxidation of ethanol at temperatures below 70 ☌.
