| Summary: | <p dir="ltr">Herein, we report the electrooxidation of glycerol in alkaline media in presence of highly active and durable NiCoO<sub>2</sub> catalyst synthesized using single step solution combustion synthesis (SCS) and compare its activity with NiO and Co<sub>3</sub>O<sub>4</sub> prepared using the same method. X-ray diffraction (XRD), X-Ray Photoelectron Spectroscopy (XPS), Scanning electron microscopy (SEM) with EDS and Transmission electron microscopy (TEM) along with EDS elemental/phase mapping were used to analyze the crystallinity, morphology and phase composition of the synthesized particles. TEM image with phase mapping confirms the existence of mixed NiCoO<sub>2</sub> and these materials shows enhanced performance when compared with individual metal oxides. The onset potential of NiCoO<sub>2</sub> is much lower and the oxidation current density obtained is relatively higher. More importantly, the current density and stability of NiCoO<sub>2</sub> obtained from chronoamperometry makes it a promising catalyst for glycerol based fuel cells.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of The Electrochemical Society<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1149/2.0401815jes" target="_blank">https://dx.doi.org/10.1149/2.0401815jes</a></p> |
