Scientists Boost Catalytic Activity for Key Chemical Reaction in Fuel Cells

Now, scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, California State University–Northridge, Soochow University, Peking University, and Shanghai Institute of Applied Physics have developed catalysts that can undergo 50,000 voltage cycles with a negligible decay in their catalytic activity and no apparent changes in their structure or elemental composition. As described in a paper published in the December 16 issue of Science, the catalysts are "nanoplates" that contain an atomically ordered Pt and lead (Pb) core surrounded by a thick uniform shell of four Pt layers.
