“…In Fig. 2b, the metallic Pt can be identified by the present of Pt 4f and Pt 4d bands located at 71.1, 74.5 eV and 314.5, 331.5 eV, which agree well with the data reported in the literature [25]. While the bands of N 1s and F 1s are not obvious in the XPS spectra of nm-Pt/PPy-HEImTfa, which suggests that most of the Pt nanoparticles are on the surface of the PPy-HEImTfa film for nm-Pt/PPy-HEImTfa.…”

“…The various ways of producing metallic-based CP nanocomposites offers wide possibilities for influencing the surface distribution of the metallic NPs at the CP/solution interface. The role of this factor in electrocatalytic performance has been demonstrated in a Pt-PANI system [120]. The electrodeposition of Pt metallic particles from PtCl 4 2-and alternatively from PtCl 6 2-solutions resulted in a difference in the shape and surface distribution of the Pt particles.…”

IntroductionSince the remarkable discovery of high electrical conductivity in polymer materials in 1977 [1], studies on conductive polymers (CP 1 ) have developed into interdisciplinary research expanding in various directions. A significant impetus to the field was given by materials scientists in their attempts to combine the unique properties of conductive polymers with those of other inorganic and organic materials. Thus, in the last two decades, research on the synthesis of CP-based composite materials has flourished and resulted in the development of a great variety of new materials with interesting specifically designed properties. The accumulation of a great number of studies on nanocomposite materials has provoked the recent appearance of several review articles [2-7] attempting to summarize, from different specific points of view, the advances made in the field. Thus, electrochemical aspects [2,7] of CP-based composites, optical and electronic properties [3], polyaniline(PANI)-based nanocomposites [4], the involvement of composites of CPs in chemical sensing [5], and the incorporation of metallocenes in CPs [6] have been extensively discussed.

Au nanoparticle-decorated polypyrrole nanotubes (defined as PPy/Au nanocomposites) are prepared by an in situ reduction process. Polypyrrole (PPy) nanotubes are prepared by a self-degraded template method, and Au nanoparticles are deposited in situ by the reduction of HAuCl(4) . The size and uniformity of the Au nanoparticles that decorate the PPy nanotubes can be controlled by adjusting the experimental conditions, such as the stabilizers used and the reaction temperature. The morphologies and optical properties of the nanocomposites have been characterized by scanning electron microscopy, transmission electron microscopy, UV-vis, and FT-IR spectroscopy. Conductivity measurements show that the conductivities of the nanocomposites decrease with a decrease of temperature, and the conductivity-temperature relationship obeys the quasi-one dimensional variable range hopping model.
