Catalytic Consequences of Chemisorbed Oxygen during Methanol Partial Oxidation on Pt Clusters

Methanol oxidation reactions on Pt clusters exhibit three distinct kinetic regimes because the requirements for the kinetically-relevant CH₃OH activation step and active-site structures vary as the coverages on Pt cluster surfaces undergo a dynamic transition from O* saturation, uncovered with intermediates, to CH₃O* saturation.
