the voltammetric performance of edge-plane pyrolytic graphite (epg) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (omz) in aqueous solution. the results revealed that the oxidation of omz is an irreversible ph-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

This research study the application of the immobilized TiO2 layer and Cu-TiO2 layer on graphite substrate as a negative electrode or anode for Li-ion battery. The titania layer was produced through chemical bath deposition method, meanwhile Cu particles were deposited electrochemically. A material can be used as an electrode as it has capability to intercalates Li ions into its crystal structur...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

Specially designed five-electrode cells contained two types of mixed ionic-electronic conductor ~MIEC! lithium-insertion anodes. These were graphite or Sn1.3Al0.3Ti1.7O1.95(PO4)3 tin composite oxide ~TCO! bonded powders sandwiched between nickel mesh current collectors as working lithium-ion anodes, with Li foils on both sides as reference electrodes, outside of which were two further Li foils,...

We have electronically wired the cytochrome P450 BM3 heme domain to a graphite electrode with the use of a pyrene-terminated tether. AFM images clearly reveal that pyrene-wired enzyme molecules are adsorbed to the electrode surface. The enzyme-electrode system undergoes rapid and reversible electron transfer, displaying a standard rate constant higher than that of any other P450-electrode syste...

Graphite material is abundantly available from recyclable sources. It possesses a good electrical conductance property, which makes it an attractive material as a working electrode. However, due to a high activation overpotential it has limited applications as compared to other solid metal electrodes. In this present work, we obtained a graphite rod from a used battery, and carried out electroc...

A Pd-encapsulated graphite electrode was used as the negative electrode in Li-ion cells. Through dispersion of ultrafine nanoparticles of palladium on the surface of graphite, the interfacial properties of the carbon surface were modified. The presence of the palladium Ž . dramatically reduces the initial irreversible capacity of the graphite in propylene carbonate PC -based electrolyte. Pallad...

Despite numerous studies presenting advances in tomographic imaging and analysis of lithium ion batteries, graphite-based anodes have received little attention. Weak X-ray attenuation of graphite and, as a result, poor contrast between graphite and the other carbon-based components in an electrode pore space renders data analysis challenging. Here we demonstrate operando tomography of weakly at...
