Density Functional Theory study of water activation and CO(sub ads)+OH(sub ads) reaction on pure platinum and bimetallic platinum/ruthenium nanoclusters

Article Abstract:

A density functional theory study of the elementary steps is presented leading to the removal of CO(sub ads(Pt)) over alloyed and sequentially deposited Pt/Ru bimetallic nanoclusters. The nanoclusters are predicted to be much more promising anode catalyst than the alloy cluster surface in fuel cell applications.

On the nature of the active state of supported ruthenium catalysts used for the oxidation of carbon monoxide: Study-state and transient kinetics combined with in situ infrared spectroscopy

Article Abstract:

The study aims on the deactivation phenomena of two differently supported ruthenium catalysts during the oxidation of CO. The study concluded that a partial deactivation was observed initially, which was identified as an activated process, both under net reducing and net oxidizing conditions.

Adsorption and coadsorption of CO and H on ruthenium surfaces

Article Abstract:

An attempt is made to study the interaction of CO with the Ru(0001) surface at several coverages and the interaction of CO with a stepped Ru(0001) surface. The lateral interaction of the CO adsorbed atop and CO adsorbed hcp is different, the hcp site having the smallest lateral interaction.
