Asunto: Lattice-strain control of the activity in dealloyed core–shell fuel cell catalysts
Lattice-strain control of the activity in dealloyed core–shell fuel cell catalysts Nature Chemistry 2, 454 (2010). doi:10.1038/nchem.623 Authors: Peter Strasser, Shirlaine Koh, Toyli Anniyev, Jeff Greeley, Karren More, Chengfei Yu, Zengcai Liu, Sarp Kaya, Dennis Nordlund, Hirohito Ogasawara, Michael F. Toney & Anders Nilsson The rational design of catalytic materials requires synthetic control over their reactive properties. Now, the activity of dealloyed Pt–Cu bimetallic nanoparticles, which catalyse the oxygen reduction reaction, can be tuned through control of the geometric strain at their surface. |
