Abstract

Synthesis of nanoparticulate Pt and PtRu were conducted in typical wet chemical approach on carbon nanocapsules (CNCs) and VXC72R for electrochemical characterization in acidic electrolyte. XRD of the as-synthesized powders indicated Pt and PtRu in FCC phase with particle sizes around 2-15 nm. Cyclic voltammetry of Pt/CNCs and PtRu/CNCs was analyzed for hydrogen oxidation reaction, revealing impressive catalytic power. In contrast, Pt/VXC72R and PtRu/VXC72R demonstrated moderately reduced performance. Our work suggested CNCs to be superb material as electrocatalyst support.
