Gold-mediated Oxidation (image) University of Houston Caption This image shows schematic representation of the lowest energy pathway for CO oxidation on gold-titania catalysts. The water layer on the titania support extends the reaction zone on the gold nanocluster and provides protons that assist in the oxygen dissociation step.
