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.
