• coefficient. There is in fact no simple relation between adsorption and diffusion energy, especially for large molecules with numerous degrees of freedom [32]. Moreover, a high adsorption energy is likely to induce surface restructuring, as observed in the present case. While such processes could be useful to

• microporous nature causes accessibility problems and diffusion limitations for large molecules and viscous fluids [2][18]. In the specific case of TS-1 [19], only molecules with a kinetic diameter of maximally 0.6 nm (e.g., benzene) can access the structure and reach the active sites. This drastically limits

• mass transfer and accessibility problems for large molecules. In Figure 1b, four nanozeolites are bridged by interparticle mesoporous voids. In Figure 1c and Figure 1d on the other hand, “real” mesopores exist in combination with micropores, but in the case of Figure 1d the mesopores are only

• affected by the presence of a surface. Iterative perturbative screening of the configuration space When we consider large molecules, the main drawback of variational calculations is the rapid growth in the number of basis functions necessary in the VCI space. As the size of the molecule increases, the
