“…Shortly after the commencement of a new millennium, carbon pastes made of (i) glassy carbon powder (with spherical particles and specially pre-treated surface) came again to the fore [48,49] as the electrode material exhibiting excellent polarisation characteristics, electrocatalytic effect for some redox systems, or even significantly improved resistivity in media with a higher content of organic solvents (such as solutions containing up to 80-90% (v/v) MeOH [50]). More favourable reaction kinetics due to electrocatalysis have also been reported for carbon pastes prepared from (ii) acetylene black [51,52], (iii) template carbon or (vi) porous carbon foam [53].…”

Abstract:In this review (with 500 refs), both electrochemistry and electroanalysis with carbon paste-based electrodes, sensors, and detectors are of interest, when attention is focused on the research activities in the years of new millennium. Concerned are all important aspects of the field, from fundamental investigations with carbon paste as the electrode material, via laboratory examination of the first electrode prototypes, basic and advanced studies of various electrode processes and other phenomena, up to practical applications to the determination of inorganic ions, complexes, and molecules. The latter is presented in a series of extensive tables, offering a nearly complete survey of methods published within the period of [2001][2002][2003][2004][2005][2006][2007][2008]. Finally, the latest trends and outstanding achievements are also outlined and future prospects given.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

“…Some original papers describe the use of unmodified electrodes made of graphite [55][56][57][58][59][60][61][62], glassy carbon [63], template carbon [64] -polymer composites, a composite based on natural and synthetic diamonds [65], nanocomposite made of carbon nanofibers [66], and a carbon-containing material prepared by a sol-gel technology [67,68]. Much attention is given for the study of electrochemical properties and application of graphiteepoxy composite electrodes [69][70][71][72].…”

The second part of the review, which covers modified carbon-containing electrodes, describes composite and microelectrodes. Electrodes made of commercial and laboratory carbon-containing composite materials are discussed. Impregnated and thick-film electrodes and microelectrodes made of carbon fibers form a separate group. Various modifiers and methods of electrode modification are presented. Prospects for the future development of solid-state modified electrodes are considered. [12][13][14][15][16]. In most cases, electrodes of these materials are modified by metal films (mercury, copper, and bismuth), molecularly imprinted TiO 2 [17]. The occurrence in the last decade of new types of carbon materials "from carbon nanotubes to edge plane pyrolytic graphite" [18,19] has significantly changed the scope and sensitivity of electroanalytical methods for the measurement of diverse targets from metals ions to biological markers. Investigators considered in detail electrochemical characteristics [20] and practical use [21] of the "edge" plane pyrolytic graphite, which proved to have a wider interval of working potentials and a low detection limit as compared to those of the basal pyrolytic graphite and GC. For example, in situ bismuth film modified edge plane pyrolytic graphite electrode was successfully applied to the ultra trace simultaneous determination of cadmium(II) and lead(II) with detection limit 5.5·10 −10 and 4·10 −10 M, respectively [22].Synthetic diamonds (nitrogen-[23, 24] and boron-doped ) have come into use quite recently for electrochemical measurements. In particular, a gold-coated, borondoped, diamond thin-film electrode was used for total inorganic arsenic detection in real water samples [50]. Unlike properties of other carbon materials, which are widely used in electroanalysis, properties of synthetic diamonds became the subject of comprehensive study just about 10 years ago. The research was hindered by two circumstances: shortage of the material and the absence of conduction. The situation radically changed with the advent of highly efficient methods for growing of polycrystalline diamond compounds.A more efficient separation, accumulation, and determination of components is achieved with electrodes of composite materials made of graphite, carbon, glassy carbon, or diamond powders and binders such as paraffin, epoxy resins, methacrylate, silicon, styrene-acrylonitrile copolymer, polyester, and silica gel. The reviews [51][52][53][54] deal with properties and applications of various composite J Solid State Electrochem

“…Los valores de k s así obtenidos fueron 5.1·10 -4 y 5.2·10 -3 cm s -1 para el electrodo de PVC/grafito y de PVC/TTF-TCNQ, respectivamente. Estos valores son similares a los encontrados para ferrocianuro sobre electrodos sólidos [18]. El incremento de la constante de velocidad heterogénea obtenido con el electrodo de PVC/TTF-TCNQ es consistente con el desplazamiento negativo observado en el pico de potencial anódico (ver Fig.…”

It was prepared a new polyvinyl chloride (PVC)/tetrathiafulvalenetetracyanoquinodimethane (TTF-TCNQ) composite electrode which showed good physical and electrochemical characteristics. Different PVC/TTF-TCNQ-graphite proportions were tested and the relation 1/10 (p/p) PVC/TTF-TCNQ provided the best results in terms of sensitivity, coefficients of variation and mechanical resistance. This electrode has interesting applications as a working electrode. So, employment is remarkable in a flow injection system and had been satisfactory checked to detect ascorbic acid. Also, the electrode exhibits selective voltammetric behaviour in aqueous solution that affords its use as an ion detector. The proposed electrode showed good kinetics property with a low background current and a relatively reproducible signal. Moreover, the electrode can be prepared in a simple way and its surface easily recovered.
