The process of electrochemical oxidation of carbon monooxide on Pt/C catalytsts with different structure of carbon support was studied. Pt/C catalysts were prepared via electrochemical dispersion of platinum electrodes under the action of an alternating pulse current. It was shown that the structure of the carbon support has a significant impact on the degree of agglomeration of platinum nanoparticles and, consequently, on the value of the specific surface area of the catalyst, but does not affect the degree of filling of platinum by carbon monoxide.
