“…The band at 1054 cm −1 (nanocompozit) and 1418 cm −1 (PEDOT) is assigned to the symmetric C-O-C ether bond. A difference that can be observed is the intensity ratio of bands the spectrum (1500 -600 cm −1 ) of nanocompozit film than PEDOT band, exhibits a clear difference in intensity [54]- [57]. This may suggest that the dopant promotes and stabilizes the structure of the film (nanocomposite).…”

Electropolymerization and characterization of poly(3,4-ethylene dioxythiophene) (PEDOT) doped with functionalized single-walled carbon nanotubes (SWANTs) polyaminobenzene sulfonic acid (PABS) and different dopants were studied. It was fabricated by a simple oxidative electropolymerization method. The nanocomposite coatings have been prepared by using electrochemical methods from aqueous solutions, such that the components were deposited onto platinum electrode substrate. The morphology of composite films was analyzed by scanning electron microscopy (SEM). The electrochemical and physical properties of the resulting composites were evaluated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Fourier transform infrared spectroscopy (FT-IR) techniques in 0.1 M LiClO4 aqueous solutions. The value of specific electrochemical capacitance of the composite films is considerably higher than that of the pure polymers films. The improved properties of the electrodes were obtained by using these composite films. The dopant substances used were sodium dodecyl sulfate (SDS) and 1,2-Dihydroxy-benzene-3,5-disulfonic acid disodium salt hydrate (tiron).

“…where n is the number of electrons participating in the redox reaction, A is the area of the electroactive surface (cm 2 ), D is the diffusion coefficient of the molecule in solution (cm 2 s À1 ) (Hrapovic and Luong 2003;Zeng et al 2006), C corresponds to the bulk concentration of the redox probe (mol cm À3 ), and c is the scan rate of the potential perturbation (V s À1 ). The FeðCNÞ redox system used in this study is one of the most extensively studied redox couples in electrochemistry and exhibits a heterogeneous one-electron transfer (n ¼ 1).…”

“…À0.25 V (vs. Ag/AgCl) decrease gradually while another peaks centered at ca. 0 V (vs. Ag/AgCl) increase as scan cycles, suggesting the formation of polyMB [33][34][35][36]. However, the current of polyMB on GO support ( Figure 3B) is much lower, which can be explained that the carboxyl on GO disrupt sp 2 networks and undoubtedly reduce the conductivity.…”

“…Besides, carbon nanotubes (CNT) were also widely employed in electrocatalysis due to its high surface area and high conductivity [28][29][30][31][32]. The CNTs/poly(phenoxazine) dye composites were employed because of their combined superior electrochemical properties [33][34][35][36]. Recently, graphene has been applied as a robust substrate for the electrocatalytic of NADH [6,[37][38][39][40].…”

Comparative Studies on Electrocatalytic Activities of Chemically Reduced Graphene Oxide and Electrochemically Reduced Graphene Oxide Noncovalently Functionalized with Poly(methylene blue)

et al. 2010

This study compares the electrocatalytic activities of chemically reduced graphene oxide (crGO) and electrochemically reduced graphene oxide (erGO), which are both noncovalently functionalized with a polyaromatic dye, poly-(methylene blue) (polyMB), toward the oxidation of b-nicotinamide adenine dinucleotide (NADH). PolyMB-crGO and polyMB-erGO composites were obtained via electropolymerization of methylene blue on crGO and GO modified glassy carbon (GC) electrodes, respectively. Cyclic voltammetry (CV) results indicate that these two types of integrated electrodes reveal different electrocatalytic activities. PolyMB-crGO integrated electrode possesses lower catalytic oxidation potential, suggesting higher catalytic activity. The present study is helpful for the understanding and screening of graphene-based advanced carbon nanomaterials for potential electrochemical applications.
