Carbon Composite Electrodes Applied for Electrochemical Sensors

Recent trends in the applications of thermally expanded graphite for energy storage and sensors – a review

“…Several studies have been reported on the thermal conductivity and electrochemical properties of TEG 103,104 . TEG also has been used in the preparation of electrochemical sensors 105 , fuel cells 106,107 , batteries 108,109 and supercapacitors 110,111 . In particular, TEG was demonstrated in lithiumion battery (LIB) with good cycling stability up to 100 cycles, first reversible capacity was 401 mA h/g 112 .…”

Decontamination of Wastewaters Containing Organics by Electrochemical Methods

“…The composite electrodes, i.e., expanded graphite-epoxy (EG-Epoxy), carbon-nanofiber expanded graphite-epoxy (CNF-EG-Epoxy), expanded graphite-silver-zeolite-epoxy (AgZEG), made using epoxy matrix were obtained from two-component epoxy resin (LY5052, Araldite / 5020 Aradur) mixed with conductive expanded graphite (EG) fillers powder and silver modified zeolite (clinoptilolite) [30][31][32]. The ratio was chosen to reach 20 weight percent (w/w) for each component, i.e., expanded graphite (EG), carbon nanofibers (CNF) (PS-447 BOX), silver-zeolite ion-exchanged function of the electrode composition.…”

“…The carbon-based composite electrodes were characterized morphologically by scanning electron microscopy and a homogeneous distribution of carbon filler within the insulating matrix was found [30][31][32]. The electrical resistance of each electrode was measured by a fourpoint resistance method [34] and the results are gathered in …”

Composite Graphite–Epoxy Electrodes for In Situ Electrochemistry Coupling with High Resolution NMR

“…The electrodes were prepared by mixing a graphite and expoxy (CaldoFix) resin. The choice in materials stems from the inherent limitation of using metallic electrodes in the detection region of the NMR spectrometer , as well as from the fact that carbon-based electrodes can be used in a wide range of applications. − Furthermore, composite electrodes have been shown to have good mechanical stability, are able to withstand a wide range of applied potentials, and are compatible with nonaqueous solvents. − In addition, the electrode’s surface can be renewed simply by polishing the material, which shows the advantages of using such electrodes and why their application in electrochemical systems has been investigated over the years. − …”
