Oxidation of formic acid and methanol on single crystal platinum electrodes
Abstract
The oxidation of formic acid and methanol involves strong adsorption prior to the charge transfer process and the intermediate formed in these reactions are even more strongly adsorbed. It has been found that these processes are highly dependent on the surface orientation of the single crystal electrodes. The highest activity has been found with (111) orientation and the lowest with (100). The highest activity of (111) orientation has been explained with the low hydrogen adsorption on this plane, and the low adsorption of strong bond intermediates which require two or three sites for their adsorption. This more than compensates for the low reactivity of the (111) plane toward formic acid and methanol themselves.
