Abstract

We report a universal method for the preparation of mesoporous Pt nanoparticles (MPNs) with tunable particle sizes. MPNs with various particle sizes are simply prepared by changing the surfactant concentration in the starting solutions. Small-sized MPNs show the highest electrochemical surface area and highest current density in the methanol oxidation reaction.
