Alloy Catalyst Beats Pure Platinum
Chemical engineers at the University of Houston have developed a new type of platinum-alloy catalyst that's four to five times better at reducing oxygen than platinum alone (Angew. Chem. Int. Ed., DOI: 10.1002/anie.200703331). The finding could be a boon to fuel cells that rely on the O2-reducing reaction. The catalyst, in the form of nanoparticles made up of a copper-cobalt-platinum alloy, . . .
