Description
|
Cylindrical catalytic mesopore model generated with PoreMS. (a) Side view of the simulation box indicating the length of the central silica block and the solvent
reservoirs. (b) and (c) Front and side view, respectively, of the pierced silica block containing the 4.8nm pore. The chemistry of the exterior surface is based on the (111) face of beta-cristobalite silica. The exterior planar and interior curved surfaces are covered with randomly distributed TMS and DMDMS groups, respectively. Two organometallic catalyst groups are attached to the interior surface in point symmetry with respect to the pore centre.
Colour code: Si atoms, yellow line; O atoms, red line; DMDMS groups, blue; TMS groups, magenta; catalyst, purple; residual surface silanol groups, yellow. |
