Novel supported catalysts: platinum and platinum oxide nanoparticles dispersed on polypyrrole/polystyrenesulfonate particles

Abstract

Platinum and platinum oxide nanoparticles are deposited on electronically and ionically conducting polypyrrole/polystyrenesulfonate particles by the reduction of Pt(NH₃)₄Cl₂ with formaldehyde and the oxidation of Na₆Pt(SO₃)₄ with H₂O₂, respectively.
