Illustration of physical confinement in porous bilayer silica film on metal catalyst

Caption

An illustration of physically confined spaces in a porous bilayer silica film on a metal catalyst that can be used for chemical reactions. Silicon atoms are indicated by the orange circles; oxygen atoms by the red circles. Nanoconfinement can occur in the pores (zero-dimensional, or 0-D) and the interface-confined region between the film and the metal (two-dimensional, 2-D).
