Diffusion-enhanced bifunctional catalysis

B. Diffusion-Enhanced Bifunctional Catalysis and THE Control of Carbon Number Distribution AND Product Functionality... [Pg.281]

The CO oxidation on PtRu is enhanced primarily because of the so-called bifunctional effect, first suggested by Watanabe and Motoo [36]. Ru is supposed to act as active sites to activate water at reduced overpotential, as OH binds stronger to Ru than to Pt (see Section 16.3.3), and CO adsorbed on Pt then reacts with OH adsorbed on Ru. It is anticipated that CO mobility will play an important role in the catalysis of this reaction. In order to test this presumption, we have employed DMC simulations to model CO diffusion on PtRu bimetallic electrodes, with the specific aim to assess the role of CO diffusion in CO electrooxidation on these surfaces [37]. [Pg.499]
