Oxygen Reduction at Palladium Decorated Copper-Molybdenum Oxide Modified Glassy Carbon Electrode

Abstract

In this study, metal nanoparticles decorated metal oxide electrode was fabricated via electrochemicaltechnique. Firstly, molybdenum/copper oxide was electrochemically deposited on the bare glassy carbonelectrode surface. Then palladium nanoparticles were modified on this oxide functionalized surface byconsecutive potential cycles. Resulting composite electrode was characterized with scanning electronmicroscopy. The proposed composite electrode was employed for electrocatalytic oxygen reduction inalkaline media. As compared to bare electrode, the resulting composite surface has tremendous effect onoxygen reduction in terms of accelerated peak current values.
