EQCM analysis of Bi oxidation mechanism on a Pt electrode

open access: yesElectrochemistry Communications, 2005
Abstract The electro-oxidation behaviours of bismuth (Bi) species adsorbed on a platinum (Pt) anode were investigated using an in situ electrochemical quartz crystal microbalance analysis in the measurement of cyclic voltammetry (CV) and electrochemical impedance spectroscopy under potentiostatic mode.

Ni Electrodeposition Enhanced by the Fe Substrate

open access: yesInternational Journal of Electrochemical Science, 2015
Electrodeposition of Ni on 316 stainless steel (ss), Ni/316 ss and Fe/316 ss electrodes was carried out in an acid bath. A Ni deposition peak (C1) was found between 0.8 and -1.2 V vs.

Investigating the Iron Plating and Stripping of Anolytes for All-Iron Redox-Flow Batteries

open access: yesJ
All-iron redox-flow batteries (AIRFB) are capable of addressing the needs for cost-effective long-term storage of renewable energies. Currently, a major limitation of AIRFB performance is the half-cell reaction of the anolyte utilising the redox couple ...

Probing the Effect of Spectator Anions on Chloride Adsorption for Selective Oxygen Evolution Reaction over Ni Catalysts

open access: yesChemElectroChem
Water electrolysis is a promising route to green hydrogen production, but its operation in chloride‐containing electrolytes (e.g., seawater) is hindered by the competing chlorine evolution reaction (CER) that lowers oxygen evolution reaction (OER ...
