Platinum monolayer core-shell nanocatalysts were shown to have excellent catalytic activities and stabilities. Usually, they are fabricated via electrochemical routes. Here, we report a surfactant-free, ethanol-based, wet chemical approach to coating Pd nanoparticles with uniform Pt atomic layers, inspired by aerobic alcohol oxidation catalyzed by the Pd cores. The as-prepared Pt monolayer electrocatalysts also exhibited high electrocatalytic performance toward the oxygen reduction reaction.
