文摘
- •
TPRS and RAIRS experiments show that adsorbed water provides a low-energy pathway for the oxidation of CO on PdO(101).
- •
Adsorbed water molecules stabilize the transition state for CO oxidation on PdO(101) via hydrogen-bonding.
- •
Water monomers and dimers promote CO oxidation on PdO(101), but the stable HO-H2O complex has a negligible influence.
