Electrocatalytic Oxidation of Vitamin B6 on a Chemically Modified Electrode

The electrocatalytic oxidation of vitamin B6 (pyridoxine hydrochloride) was demonstrated on a Nafion/lead ruthenate pyrochlore modified electrode (designated as NCME) by cyclic voltammetry. The catalytic activity of vitamin B6 was explored in terms of the higher oxidation state of ruthenium species, i.e., Py-Ru/Ru in the pyrochlore network (Py). The mediated mechanism was derived by Michaelis-M...

Graphite Electrode Modified with a New Phenothiazine Derivative and with Carbon Nanotubes for NADH Electrocatalytic Oxidation

The electrochemical behavior of a modified electrode obtained by immobilization of single-walled carbon nanotubes onto a graphite electrode modified with a new phenothiazine derivative, bis-phenothiazin-3-yl methane (BPhM), G/BPhM-CNT, has been evaluated and compared with BPhM adsorbed on graphite electrode (G/BPhM). The G/BPhM-CNT electrode presents improved performances for NADH electrocataly...

Electrocatalytic oxidation of glucose on the modified carbon paste electrode with sodalite nanozeolite for fuel cell

In this study, a sodalite nanozeolite was synthesized and characterized by X-ray diffraction (XRD) and scanning electronic microscopy (SEM). Following the morphology evolution of the sodalite nanozeolite in the SEM images illustrates the formation of the spherical particle with a size between 60 and 80 nm. Then, carbon paste electrode (CPE) was modified by sodalite nanozeolite and Ni2+ ions. Th...

Electrocatalytic determination of free glycerol in biodiesel at nano nickel modified graphite electrode

For the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (Ni) modified composite graphite (CG) electrode (hcp-nano Ni/CG) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 M KOH). The hcp-nano Ni/CG electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare CG. The elec...
