Controlled access systems can employ various mechanisms to regulate the interaction between catalysts and reactants:
- Porous Materials: Using materials with tailored pore sizes to control the diffusion of reactants to the active sites. - Encapsulation: Encapsulating catalysts within nanoreactors or micelles to create a controlled microenvironment. - Gatekeeping Molecules: Utilizing molecules that can selectively permit or restrict access to catalytic sites based on the size, shape, or chemical nature of the reactants. - Surface Modifications: Modifying the surface of catalysts with functional groups to control the adsorption and desorption of reactants.
