Membranes can enhance catalysis in several ways: - Selective Permeation: By allowing only certain molecules to pass through, membranes can increase the concentration of reactants near the catalytic site, improving the reaction rate. - Separation of Products and Reactants: Membranes can separate reaction products from reactants in real-time, driving reactions to completion and reducing the need for downstream separation processes. - Controlled Environment: Membranes can create a controlled environment, regulating factors like temperature and pressure, which are crucial for optimal catalytic activity.
