These electrodes have found wide applications in various electroanalytical techniques, including voltammetry, amperometry, and impedance spectroscopy. In voltammetry, carbon SPEs are used to study the electrochemical behavior of different substances by measuring the current as a function of applied potential. ...
The electrochemical CO2 reduction reaction (CO2RR) powered by renewable energy to produce valuable chemicals and fuels has become a promising strategy for using renewable energy to produce fuels and chemicals. The process can occur under ambient temperature and normal pressure conditions. This approach potentially aids in mitigating the climate change problem by initiating a carbon-neutral cycle. ...
Cyclic voltammetry (CV) is the backbone of most electrochemical research and is an essential electrochemical technique that allows researchers to explore candidate catalysts in greater depth. ...

Electrochemical experiments are performed by delivering and controlling a potential or current signal to the electrochemical cell/device under test and measuring its response through a potentiostat/galvanostat (PGSTAT). Here, two different options for performing different electrochemical experiments are discussed: linear and staircase scans, as well as some applications where one may be preferred ...
The capacitance and electrical conductivity of the carbon composite electrodes were then examined using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), respectively. ...
Electrochemical studies based on linear sweep voltammetry (LSV) and cyclic voltammetry (CV) prove that the OEP for the SnO2 electrode was much higher than that of the PbO2 electrode, and the electron-transfer kinetics and the reversibility of electrode reaction of the SnO2 electrode were superior to those of the PbO2 electrode. ...
The steady voltage with potassium permanganate electrodes was nearly twice that of with potassium ferricyanide. Cyclic voltammetry curves confirmed that the potassium permanganate had higher catalytic activity than potassium ferricyanide. ...
In the presence of lauric acid pretreated inoculum, MFC produced maximum volumetric power density of 4.8 W/m3 and the CE increased from 3.6% (for untreated inoculum) to 11.6%. Cyclic voltammetry (CV) and electro-kinetic evaluation indicated a higher bio-catalytic activity at the anode of the MFC inoculated with lauric acid pretreated sludge. ...
Our gCNMs are prepared from C, N-containing precursors treated at different temperatures. Cyclic voltammetry showed clear oxidation/reduction cycles in the 0.5–1.5 V range indicating that Li + intercalation took place resulting in electric conduction properties of the previously semiconducting material. ...
Polyaniline films were deposited on marine grade 5083 aluminium, and were examined and characterised with the use of cyclic voltammetry, UV–Vis spectroscopy and SEM imaging. The polyaniline films were electrochemically synthesised from 0.5 M oxalic acid solutions containing 0.1 M aniline, under potentiostatic control. ...
However, these methods have various disadvantages such as long time requirements, low sensitivity, interfering agents etc. Cyclic voltammetry at inert electrodes is another method for antioxidant determination. ...
This oxidisability was related to oxidation and reduction peaks seen in cyclic voltammograms in 0.1 M HCl of powders dispersed on a glassy carbon electrode. With the pH 4 to 7 samples, a single oxidation peak was seen in the voltammograms at a low potential (c. 0.12 V (Ag/AgCl)), in contrast to the multiple peaks for samples with a regular polyaniline structure.Keywords: aniline ...
Particulate electrodes (TiO2/Ti and TiO2/ITO) have been shown to notably favour charge-carrier transfer at the electrolyte interface while a thermal electrode (Ti) has been shown to favour charge-carrier separation when applying an electric potential bias according to cyclic voltammetry technique, as a consequence of differences in TiO2 surface between ...
The morphologies, chemical composition and conductivity of nanowires were evaluated by means of Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT–IR) and cyclic voltammetry (CV). The obtained nano–wire is around 50 nm in diameter with large surface, good conductivity. By surface enhanced Raman spectroscopy, the amine groups of ...
We describe the process of modification of the platinum (Pt) nanowire surface and subsequent immobilisation of enzyme glucose oxidase (GOx) on Pt nanowires (PtNWs) for direct glucose measurement. A cyclic voltammetry technique was used to measure electrochemical oxidation between GOx and glucose. ...
This experiment was conducted to establish a system for detecting trace cobalt ions in water and plant tissues using a voltammetric in vivo sensor. Cyclic and stripping voltammetry was devised from hand-made, macro-type implantable three-electrode systems. ...
Cyclic voltammetric studies of Pd(II)/Pd(0) electrode process were carried out on a Glassy Carbon Electrode (GCE) in HCl for the development of an Anodic Stripping Voltammetric (ASV) method for the determination of palladium in High–Level Nuclear Waste (HLNW). ...
Prior to the application of the electrooxidation for HA degradation the electrochemical behavior of BDD electrode in HA containing 0.1M Na2SO4 supporting electrolyte was studied by cyclic voltammetry (CV), and the working conditions of bulk electrolysis corresponding to water decomposition potential range were selected. ...
