Figure 8. (A) Depiction of hypothesized H⁺/H₂O-aided diffusion of Cu⁺ and NH₃ inhibition within SSZ-13 to form Cu dimers relevant to the proposed catalytic methane oxidation cycle. Single O atoms may correspond to framework zeolite O atoms or coordinating H₂O molecules. Reprinted with permission from ref^[117]. Copyright 2019.
