A review about the surface resistance technique in electrochemistry
Abstract The use of the surface resistance changes as an alternative method to study the electrochemical interface is reviewed considering both experimental and theoretical aspects. ParticularExpand
The effect of pH on the charge transport at redox polymer-modified electrodes: an a.c. impedance study applied to poly(o-aminophenol) film electrodes
Impedance spectroscopy was used to study the effect of solution pH on the electrochemical behavior of poly(o-aminophenol) (POAP) modified electrodes. An a.c. impedance expression was derived on theExpand
Spectroscopic Characterization of Poly(ortho-Aminophenol) Film Electrodes: A Review Article
This paper refers to spectroscopic studies carried out to identify the products of o-aminophenol electro-oxidation and elucidate the structure of electrochemically synthesized poly(o-aminophenol)Expand
Deposition and stripping processes of tin on gold film electrodes studied by surface conductance
Abstract The CV and surface conductance (SC) responses of tin species adsorbed on evaporated gold film electrodes were studied as a function of the potential window and the potential sweep rate. SnExpand
Electrosynthesis and Spectroscopic Characterization of Poly(o-Aminophenol) Film Electrodes
This review, which is divided into three parts, concerns electrochemical synthesis, spectroscopic characterization, and formation mechanisms of poly(o-aminophenol) (POAP) film electrodes. The firstExpand
Constant phase element behavior in the poly(o-toluidine) impedance response
Abstract The impedance response of polymers derived from aryl amines and ring-substituted aryl amines shows a CPE behavior at low frequencies with α between 0.5 and unity. In this work, theExpand
Impedance characteristics of poly-o-aminophenol electrodes
The impedance characteristics of poly-o-aminophenol film electrodes in NaClO4 0.4 M + HC1O4 0.1 M electrolyte have been measured in the frequency range 0.01 <f< 103Hz and at two differentExpand
Electropolymerization of o-aminophenol on Different Electrode Materials and in Different Electrolyte Media: Formation of Poly(o-aminophenol) Film Electrodes
Oxidation of o-aminophenol on different electrode materials (gold, platinum, carbon, indium-tin oxide, etc.) in aqueous medium was shown to form poly-o-aminophenol (POAP). Like aniline, o-AP can beExpand
The charge transport process at gold electrodes modified by thick nickel hydroxide films. A study employing rotating disc electrode voltammetry in the presence of the Fe(CN)63 −/4 − redox couple
Abstract Rotating disc electrode voltammetry (RDEV) was employed to study the transport properties of nickel hydroxide films electrochemically deposited on gold in the presence of the Fe(CN)63 −/4 −Expand
