The surface-science approach coupled with industrial catalyst research
offers a synergistic strategy to improve the performance of industrial catalysts.
The poorly understood microscopic processes that determine the structural deactivation
of ruthenium-based catalysts during CO oxidation have been elucidated.
Based on these results measures are proposed to improve the performance of ruthenium catalysts.
