Ultrafine jagged Pt nanowires extremely efficient ORR catalysts; 50x more power than current commercial catalyst

Green Car Congress

An international team led by researchers at UCLA and Caltech has demonstrated that altering the form of platinum nanoscale wires from a smooth surface to a jagged one can significantly reduce the amount of precious metal required as a catalyst for the oxygen reduction reaction (ORR) in fuel cells and thus lower the cost.
