Description
The current study addresses the superior electrocatalytic activity of nickel oxide nanoparticles (nano-NiO x) modified GC, Au and Pt electrodes towards the OER. The electrodeposition of nickel oxide nanoparticles (with an average particle size of 80 nm) are believed to enhance the OER reaction. NiOOH phase, as shown from XRD data, participates in the OER mechanism in such a way to facilitate the charge transfer during various steps in the reaction mechanism through a reversible transformation of NiOOH to NiO 2. Optimizing the loading level and the operating pH of the proposed catalyst has been carried out. © 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
