Researches on chemically modified electrodes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986
Abstract A novel electrochromic film of vanadium hexacyanoferrate (VHF), an analogue of mixed-valence-compound Prussian blue, was deposited electrochemically on a platinum substrate for the first time. The preparative conditions, electrochemical properties and infrared spectra of the VHF film were investigated in detail.

Chemically Modifying Electrodes in 3D

ECS Meeting Abstracts, 2014
Carbon aerogels, nanofoams, nanofoam-filled carbon papers, and related ultraporous nanoarchitectures are attractive electrode materials for electrochemical sensing, catalysis, and energy storage/conversion applications because of their conductive carbon framework and inherent characteristics of high surface area and through-connected networks of ...

Chemically modified electrodes

1988
The electrochemical reduction of silver ions and the understanding of limiting currents by Solomen (1) was perhaps the first indication that voltammetry could be analytically useful. However, it was not until the introduction of a practical, reproducible working electrode, the dropping mercury electrode (DME), that the analytical utility of the ...

Chemically modified electrodes

2005
The historical development of chemically electrodes is briefly outlined. Following recent trends, the manufacturing of modified electrodes is reviewed with emphasis on the more recent methods of electrochemical polymerization and on new ion exchanging materials. Surface derivatized electrodes are not treated in detail.

Calixarene-Poly(dithiophene)-Based Chemically Modified Electrodes

Chemistry - A European Journal, 2001
The stepwise synthesis of cone and partial cone 1,3-bridged n-propoxy-calix[4]crown ethers ("monomers" 2 and 3) with an electropolymerizable 2,2'-dithiophene-3-yl-hexylene functionality at the lower rim, is described. The potential of 2 and 3 as sensing agents for alkali metal ions was investigated by 1H NMR titration experiments with NaSCN and KSCN ...

Chemically modified electrodes in liquid chromatography detection: A review

Talanta, 1991
Recent trends in the use of chemically modified electrodes (CMEs) in electrochemical detection systems used in flow-injection analysis or high-performance liquid chromatography are reviewed, with the objective of indicating the most promising approaches for practical CME applications.

The potentiometric response of chemically modified electrodes

Analytica Chimica Acta, 1996
Abstract The electrochemical polymerization of ortho-methoxyaniline and ortho-methylaniline was studied on platinum electrodes. The electrochemical response of electropolymerized films exhibits three well-defined redox processes similar to those observed for polyaniline.
