The detailed molecular steps that occur when carbon monoxide is oxidized to carbon dioxide on a catalytic gold-titanium dioxide surface have for years been uncertain and controversial, despite intense study.

A collaborative team in Texas has used a combination of experiment and theory to determine, for the first time, exactly how the reaction works and the key role water plays in it (Science 2014, DOI: 10.1126/science.1256018). The findings help clarify earlier but less comprehensive work, . . .
