“…After the electrodeposition of PB, the typical peaks for the iron regions were observed, which indicate that Fe exists in both the Fe(II) (708.5 eV) and Fe(III) (710.9 eV) states (Insert of Figure 4(b)). 31,32 Amperometric Response of PPy/PB Nanowire Modified Electrode to H 2 O 2 Sensing. PB is known to be a superior electrocatalyst for H 2 O 2 because of its reduced form, Prussian white, which has the capacity to catalyze the reduction of H 2 O 2 at a rapid catalytic rate with a low overpotential, as shown by eq.…”

A hydrogen peroxide sensor based on a polypyrrole (PPy)/Prussian blue (PB) modified electrode was developed. PPy nanowires were prepared by one step template-free electrochemical polymerization on a gold electrode and a PB layer was deposited using an electrochemical method. The introduction of the PPy nanostructure can provide a high surface area and lead to high sensitivity to hydrogen peroxide. The surface morphology of the PPy/PB electrode was characterized by scanning electron microscopy (SEM). The structural features of the PPy/ PB electrode were confirmed by attenuated total reflection infrared (ATR-IR) and X-ray photoelectron spectroscopy (XPS). Chronoamperometry (CA) was used to evaluate the sensitivity of the sensor towards hydrogen peroxide.

“…[25][26][27] These nanostructures are often used as precursors of metal oxide or soft templates of other nanomaterials. [28][29][30][31][32] From a fundamental viewpoint, it is highly desirable to understand the mechanism between metal ions and ligands because of their potential applications in the detection of metal ions, water treatment and drug delivery.…”

Cobalt ion-based coordination polymer nanowires were synthesized by using nitrilotriacetic acid (NA) as a chelating agent by a one-step hydrothermal approach. In the synthesis, cobalt ions were bonded with amino or carboxyl groups of NA to form one-dimension polymer nanowires, which can be confirmed by FTIR and TGA results. Our experimental results show that the morphologies of polymer nanowires greatly depend on the precursor salts, ratios between deionized water and isopropyl alcohol. The probable molecular formula and growth mechanism have been proposed. After heat treatment, the cobalt ion-based coordination polymer nanowires can be converted into porous Co(3)O(4) nanowires, which completely preserved the nanowire-like morphology. When used as anodes in lithium-ion batteries, the obtained porous Co(3)O(4) nanowires exhibited a high reversible capacity of 810 mA h g(-1) and stable cyclic retention at 30th cycle. The good electrochemical performance could be attributed to the porous nanostructure of Co(3)O(4), which provides pathways for easy accessibility of electrolytes and fast transportation of lithium ions.

“…While electrical properties are of prime interest, thermal properties of PPy [14] have not been virtually reported in the literature despite their vital importance particularly in the design of composites. The dierence in the thermal properties of the components, such as thermal expansion, can determine lifetime of those materials.…”

Thermal properties of polypyrrole nanotubes synthesized by the chemical oxidation of pyrrole with iron(III) chloride in the presence of methyl orange as structure-guiding template, have been investigated. As-prepared polypyrrole salt and corresponding base were compressed into pellets. Thermogravimetric analysis has shown that the heating/cooling of both polymers is connected with water desorption/re-absorption. This process inuences all temperature dependences of the thermophysical properties. The specic heat of both polypyrrole forms was the same at 35• C. The thermal diusivity of polypyrrole base was lower than that of the salt. The dilatational characteristics are strongly inuenced by water desorption/re-absorption. Water desorption is connected with the contraction of polypyrrole and its re-absorption with the expansion of polypyrrole. The electrical resistivity was measured, in analogy to thermal experiments, by a four-point van der Pauw method. The electrical resistivity was 0.016 and 10.2 Ωcm at room temperature, for both materials. The electrical resistivity was also inuenced by water desorption/re-absorption as well as other thermophysical properties.
