Abstract
Platinum (Pt) nanoparticles were prepared by the liquid-phase reduction of tetraammineplatinum (II) chloride ([Pt(NH3)4]Cl2) using Nafion as a stabilizer under various conditions of the Nafion phase. This method is novel in its use of electrostatic interactions between the Pt complex ions and sulfonic groups in the hydrated Nafion molecules. The synthesized Pt nanoparticles of the recast film system had a cubic shape. In the case of the Nafion solution system, the Pt nanoparticles mainly had a spherical shape. The shapes and sizes of the Pt nanoparticles were strongly influenced by the Nafion phase.
