Copper bromide modified copper electrode was prepared and used to electrocatalytic oxidation of ethanol.
Scanning electron microscopy and energy dispersive x-ray experiments suggested the formation of thin layer
of copper bromide on the copper surface. The j0for copper bromide modified copper and copper chloride
modified copper electrodes are 9.8 and 5.7 folds respectively higher than for that of bare copper electrode. For
copper bromide modified copper electrode, the charge transfer coefficient (α) and the number of electrons
involved in the rate determining step (nα) were calculated as 0.44 and 1 respectively.
