Atomically dispersed noble metal catalysts have received recent interest, although the coordination of the metal to the support and how this is influenced by pre-treatment have not often been elucidated. We combine CO FTIR-TPD and DFT to distinguish how catalyst reduction via CO or H₂ influence the local metal coordination and molecular desorption processes.
