Pore diameter (dp) for channel-like PMSs according to the BJH pore size distribution, which, however, underestimates the effective pore diameter by circa 1.0 nm, as shown by theoretical and geometrical calculations [48, 49] pore diameter of cage-like PMSs according to Ravikovitch and Neimark [50], 

Pore-confinement of the catalytically active center may have favorable effects as demonstrated for (i) protection of the reactive sites from deactivation processes 

The siliceous surface provides various reactive sites that have been assigned to distinct silanol groups (isolated, perturbed isolated, vicinal, geminal) and strained
