Electrocatalysis by ad-atoms Part III. Enhancement of the oxidation of carbon monoxide on platinum by ruthenium ad-atoms

Enhancement of carbon monoxide oxidation on platinum by ruthenium ad-atoms was found to take place in two θRu regions; one by the increase of (nPt−Ru)av and another by the increase of (nRu−Ru)av, as expected from the standpoint of the bi-functional theory proposed by the authors.
