After sufficient D 2 O adsorption, the reaction cell was thoroughly evacuated (to ∼10 −6 ar) at 120 C (the boiling point of D 2 O is 101.4 C). No remarkable difference was observed on the C-face before and after D 2 O adsorption, suggesting that D 2 O was weakly interacting with the C-face and thermal heating allowed full desorption of D 2 O.
