Enhanced electrochemical oxidation of methanol on copper electrodes modified by electrocorrosion and electrodeposition
In this paper, we report a study of electrocatalytic oxidation of methanol on copper electrodes subjected to different surface treatments, either electrocorrosion or electrodeposition in the absence of strong hydrogen co-deposition. The surface morphology of treated electrodes was examined by Field...
