On mechanistic differences in methanol oxidation in basic medium induced by the activation of gold electrodes

A comparative study of methanol oxidation on normal and polycrystalline gold electrodes activated by square wave potential sweep in a basic medium has been performed. The differences in kinetic parameters obtained can be attributed to changes in the bond energy of OH on both forms of gold, whereas t...

Description
Summary:A comparative study of methanol oxidation on normal and polycrystalline gold electrodes activated by square wave potential sweep in a basic medium has been performed. The differences in kinetic parameters obtained can be attributed to changes in the bond energy of OH on both forms of gold, whereas the corresponding changes in intensity obtained are the consequence of the change in the surface area induced by the activation.
