Abstract

Nanostructured PtW alloys on carbon support have been synthesized by various approaches. The morphology and particle size of the prepared alloy catalysts were characterized by high resolution electron transmission microscopy (HRTEM), high angle annular dark field-scanning transmission electron microscopy (HAAF-STEM), and X-ray diffraction (XRD). The electrocatalytic activity of RW alloys were examined by rotation disk electrode (RDE) technique. The results have shown that the particle size and morphology of PtW electrocatalysts greatly depend on the synthetic approaches. Well alloyed PtW phase and uniform size distribution are important to achieve high activity for oxygen reduction reaction (ORR). The prepared, carbon supported PtW alloys are twice more active than commercial Pt/C for ORR in acid electrolyte, and will be the potential candidate as cathode electrocatalyst for PEMFCs. copyright The Electrochemical Society.
