More than skin deep: Platinum monolayers can act as shells for palladium nanoparticles to lead electrocatalysts with high activities and an ultralow platinum content, but utilization. The stability derives from the core protecting shell dissolution. In fuel-cell tests, no loss of was observed in 200 000 potential cycles, whereas significant.
