The Energy Race and the search for commodity catalyst materials

By Eileen De Guire / June 14, 2011

Illustration of the way the electronic configuration of metal ions can control the activity of metal oxides for oxygen reduction, varying it by a factor of at least 10,000 times. This can serve as a design principle (symbolized as a “volcano plot”) to screen metal oxide candidates and accelerate the development of efficient fuel cells,…

Less platinum, better efficiency for fuel cells

By / August 20, 2010

The multimetallic nanoparticle created by Brown University chemists for fuel-cell reactions uses a palladium core and an iron-platinum shell. Credit: Sun Lab/Brown University According to a Brown University press release, researchers have created a unique core-and-shell nanoparticle that uses less platinum yet performs more efficiently and lasts longer than commercially available pure-platinum catalysts at the…
