abstract = {Direct ethanol fuel cells are attractive power sources
based on a biorenewable, high energy-density fuel. Their
efficiency is limited by the lack of active anode materials
which catalyze the breaking of the C−C bond coupled to the
12-electron oxidation to CO2. We report shape-controlled
PtNiRh octahedral ethanol oxidation electrocatalysts with
excellent activity and previously unachieved low onset
potentials as low as 0.1 V vs. RHE, while being highly
selective to complete oxidation to CO2. Our comprehensive
characterization and in situ electrochemical ATR studies
suggest that the formation of a ternary surface site
ensemble around the octahedral Pt3Ni1Rhx nanoparticles plays
a crucial mechanistic role for this behavior.},
