Carbon supported Au–PtRu (Au–PtRu/C) catalysts were prepared as the anodic catalysts for the direct methanol fuel cell (DMFC). The procedure involved simple deposition of Au particles on a commercial Pt–Ru/C catalyst, followed by heat treatment of the resultant composite catalyst at 125, 175 and 200°C in a N 2 atmosphere. High-resolution transmission electron microscopy (HR-TEM) measurements...
Methanol oxidation on carbon-supported Pt–Ru–Ni ternary alloy nanoparticles was investigated based on the porous thin-film electrode technique and compared with that on Johnson–Matthey Pt–Ru alloy catalyst. Emphasis is placed on the effect of alloying degree on the electrocatalytic activity and stability of the ternary catalysts. The as-prepared Pt–Ru–Ni nanoparticles exhibited a single phase fcc...
