“…The stability of the 3APCP film at the GC surface versus the applied potential was evaluated by a series of CV voltammograms acquired in the presence of the of Fe(CN)6 3−/4− redox probe. Ho et al developed a template-free synthetic procedure for preparing a conducting metal-doped polymer nanocomposite [92]. The study, performed by CV/TEM/EDX/FTIR/XPS techniques, implied using PPY, HAuCl4 and 4-sulfocalix [4]arene as a reductant, oxidant and dopant, respectively.…”

Abstract:The characterization of chemically modified sensors and biosensors is commonly performed by cyclic voltammetry and electron microscopies, which allow verifying electrode mechanisms and surface morphologies. Among other techniques, X-ray photoelectron spectroscopy (XPS) plays a unique role in giving access to qualitative, quantitative/semi-quantitative and speciation information concerning the sensor surface. Nevertheless, XPS remains rather underused in this field. The aim of this paper is to review selected articles which evidence the useful performances of XPS in characterizing the top surface layers of chemically modified sensors and biosensors. A concise introduction to X-ray Photoelectron Spectroscopy gives to the reader the essential background. The application of XPS for characterizing sensors suitable for food and environmental analysis is highlighted.

“…Considered as the most commercial value of conducting polymer materials, polypyrrole (PPY) has been widely studied because of its high electrical conductivity, biocompatibility, electrocatalytic activity, and good environmental stability. PPY and its composites have been applied in catalysts , sensors , supercapacitor electrode materials , drug delivery materials , electrically switched ion exchange , heavy metal extraction , and so on. Furthermore, PPY and its nanocomposites were also used as adsorbents of Hg(II) ion , nitrate , and Cr(VI) ion from wastewater.…”

Lignosulfonate‐polypyrrole (LS‐PPY) composite nanospheres were prepared facilely via an in situ polymerization of pyrrole monomers in the presence of lignosulfonate as a dispersant and ammonium persulfate as an oxidant. The LS‐PPY composite was characterized with Fourier Transform infrared spectroscopy (FTIR), thermogravimetric analysis, wide‐angle X‐ray diffraction (XRD), scanning electron microscopy (SEM), field‐emission SEM, and transmission electron microscopy. Uniform LS‐PPY solid composite nanospheres with an average diameter of 154 nm were obtained. The LS‐PPY composite nanospheres were applied to adsorption of Ag(I) and Pb(II) ions from aqueous solutions. Maximum adsorption capacities of Ag(I) and Pb(II) were up to 759.3 mg g−1 and 207.5 mg g−1, respectively. Furthermore, the silver ions can be reduced to metallic silver nanowires through a redox reaction between the LS‐PPY composite nanospheres and the silver ions. A productive no‐template route to fabrication of LS‐PPY composite nanospheres with controllable size and heavy‐metal‐ion adsorption ability was achieved. POLYM.
