Abstract
Platinum (Pt)-based alloys are effective catalysts for oxygen reduction reaction (ORR) or fuel oxidation in proton exchange membrane fuel cells (PEMFCs). A wet-chemical approach for preparing monodisperse PtNi, PtCo and PtFe nanocubes and PtNi nanoctahedra which are terminated with {100} and {111} facets, respectively, were developed. Such nanoscaled electrocatalysts supported on carbon black with controlled shape, e.g., octahedral configuration, is provided. ORR activity on the PtNi nanoctahedra is ˜5.1 fold higher than that of nanocubes with a similar size, and their C-supported samples are highly active with respect to commercial Pt/C.
