Influence of chemical environment on the surface structure of Pd-iC-CeO₂. (A) CO-ATR of Pd-iC-CeO₂ under pristine, aqueous, and 0.5 M H₂O₂ solutions (B) ATR deconvolution of individual MtM surface states at temperature after simulated reaction conditions in either pure D₂O or 0.5 M H₂O₂/D₂O conditions. Conditions: 10%CO/He or pure CH₄ using 2 mL of D₂O or 0.5 M H₂O₂ in a trough configuration measured in a static gas atmosphere simulating batch condition, conditions for reaction 10 mg catalyst suspended in either D₂O, 0.5 M H₂O₂, or mixtures of D₂O/H₂O₂, as indicated, and reacted in sealed ATR cell under 20 psig gas pressure for 1 h.
