Electrocatalysis by ad-atoms: Part III. Enhancement of the oxidation of carbon monoxide on platinum by ruthenium ad-atoms
Masahiro Watanabe,Satoshi Motoo +1 more
TL;DR: In this paper, the authors found that carbon monoxide oxidation on platinum by ruthenium ad-atoms was found to take place in two θ Ru regions; one by the increase of ( n Pt−Ru ) av and another by an increase of n Ru−Ru av, as expected from the standpoint of the bi-functional theory proposed by the authors.
