Preparation of Shape-Controlled Pt nanoparticles by Galvanostatic Electrolysis

摘要

Low concentration of platinum ions, which were produced by oxidative dissolution of the Pt anode during galvanostatic electrolysis, were reduced at the graphite cathode to form Pt nanoparticles with a cubic structure. This could be ascribed to slow Pt deposition which would be dominated by the diffusion of platinum ions.
