Highly Dispersed

Bimetallic AuPt catalysts were synthesized via a facile capping agent-free route. Compared to the catalysts with too much Pt on the surface, the surface Pt-rich catalysts with a few exposed Au atoms exhibit the enhanced methanol oxidation reaction activity due to the stronger synergistic effect between Pt and Au.
