Abstract :In this study, metal nanoparticles decorated metal oxide electrode was fabricated via electrochemical technique. Firstly, molybdenum/copper oxide was electrochemically deposited on the bare glassy carbon electrode surface. Then palladium nanoparticles were modified on this oxide functionalized surface by consecutive potential cycles. Resulting composite electrode was characterized with scanning electron microscopy. The proposed composite electrode was employed for electrocatalytic oxygen reduction in alkaline media. As compared to bare electrode, the resulting composite surface has tremendous effect on oxygen reduction in terms of accelerated peak current values.
Keywords : Oxygen reduction, Pd nanoparticles, Molybdenum and Copper oxide
