dc.description.abstractThis work was conducted in order to establish the behavior of Ir@Pt core@shell nanoparticles (NPs) during the catalysis of the ethanol oxidation reaction (EOR). Ir@Pt catalysts with < 1 monolayer of the Pt shell were synthesized using the well-established polyol method, which involves the use of a capping ligand. The NPs were tested for the EOR at both room and elevated (70 ̊C) temperatures, as well as acetaldehyde oxidation at room temperature. Ir was found to be more active towards the EOR at lower potentials and Pt at higher potentials. The presence of the capping ligand made it difficult to establish any cooperativity between the two metals to catalyze the EOR. Thus, similar Ir@Pt NPs were also made without a capping ligand. Unexpectedly, little to no enhancement of the EOR catalytic activity was found for these core@shell NPs. The findings were compared to similar studies of methanol oxidation.en_US
