Phenformin Effect on the Anodic Dissolution of Nickel in Acid Media

Abstract

A kinetic model has been put forward to account for experimental results, wherein the electrical elements measured by electrochemical impedance spectroscopy (EIS) are related to the kinetic constants of the aforementioned mechanism. In here, mass transport is virtually absent (or considered as very big and hence negligible). High concentrations of phenformin hydrochloride favour its adsorption onto the nickel surface and its subsequent reaction with corrosion products, thus making it able to inhibit the electro-dissolution of nickel.

Voltammetric Characterization of Nickel Hydroxide Grown on Nickel/Epoxy Moldable Electrodes

“…Nickel-based composite materials have indeed shown promising characteristics as electrodes for capacitors/supercapacitors [65], even at the nanoscale [66,67]. Further characterization work on such electrochemical systems is underway and a report will be submitted [68]. were added in minimum amounts as cross-linker and to obtain a paste, respectively.…”
