Preparation of polypyrrole (PPy) containing Pt nanoparticles was attempted. The oxidation of pyrrole into polypyrrole proceeded by H2PtCl4, simultaneously reducing Pt(IV) to Pt(0). The Pt particles were obtained with average size of 2 nm and fairly narrow size distribution. Moreover, the maximum content of Pt reached over 20 wt% without any evidence of aggregation. The optimum [Pt]/[Py], for obtaining successful Pt/PPy composite including highly concentrated Pt and exhibiting high electrical conductivity, was determined at R = 0.6.
