Abstract
The electrochemical oxidation of COad was investigated on smooth and h igh area platinum, platinum-tin and platinum-ruthenium electrodes. On high area platinum, COad was classified into two types by their oxidat ion potentials: an easily oxidized one and one which is hard to oxidiz e. Pt-Ru was found to promote the oxidation of the latter, whereas Pt- Sn did the same for the former. The ternary system, Pt-Ru-Sn, showed e ven higher catalytic activity for COad oxidation than the binary syste ms. (C) 1998 Elsevier Science S.A.
