Turnover rates for n-hexene isomerization are higher in 8-MR pockets of MOR than in 12-MR channels and monomolecular ethanol dehydration is selectively catalyzed by OH groups in 8-MR pockets. These findings open opportunities for design of shape-selective zeolite catalysts by the rational positioning of acid sites within specific channel environments.
