Goldeneye : A model for CO oxidation on gold electrodes in alkaline media is presented, and it assumes that CO enhances the adsorption of its own oxidant. This model explains a reaction order larger than 1, and that dissolved CO was easier to oxidize than adsorbed CO. DFT calculations confirmed that CO and OH enhanced each other′s binding on the Au(111) surface. C black, O red, H gray.
