Identification of bimetallic electrocatalysts for ethanol and acetaldehyde oxidation: Probing C2-pathway and activity for hydrogen oxidation for indirect hydrogen fuel cells

- Electrocatalysts exhibited different activities for the EOR.
- Nanoparticle composition played important role on the selectivity for the EOR.
- W/Pt/C presented high selectivity for the C2-pathway.
- W/Pt/C showed higher activity for the HOR and was tolerant to acetaldehyde.
