Conducting poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) composites containing Pt nanoparticles were synthesized by one-step method. Pt nanoparticles were formed in commercial PEDOT:PSS solution by hydrothermal reaction, alcohol reduction, and electron exchange with PEDOT and stabilized by PSS [PtCl 6] 2- ions reduced completely after 4 h and Pt nanoparticles of arbitrary diameter in the range 3.0-5.0 nm were obtained. Considering refluxing time, slightly increased and narrow-sized Pt nanoparticles were stabilized and immobilized in the conducting polymer, PEDOT:PSS matrix. The formation and growth of Pt nanoparticles were characterized by using X-ray diffractometer, transmission electron microscopy, X-ray absorption spectroscopy, and X-ray photoelectron spectroscopy. Furthermore the electrostatic or chemical interaction between Pt nanoparticles and PSS - chain was also confirmed.
