Platinum Nanoparticles-Cobalt Oxide Nanostructures As Efficient Binary Catalyst For Ethylene Glycol Electro-Oxidation, Ghada El-Nowihy

Chemical Engineering

An enhanced electrocatalytic activity towards ethylene glycol oxidation reaction (EGO) in alkaline medium is observed at a glassy carbon (GC) electrode modified with a nanoparticle-based binary catalyst composed of Pt (nano-Pt) and cobalt oxide (nano-CoOx). The electrocatalytic activity of the modified electrodes towards EGO depends on the loading level as well as the composition of the catalyst layer atop the GC electrode surface. Several techniques including cyclic voltammetry (CV), field-emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray spectroscopy (EDS) are used to address the catalytic activity of the proposed catalyst and to reveal their surface morphology and composition, respectively. …
