Microreactors: These small-scale reactors improve mass transfer and heat management, enhancing the efficiency of catalyst delivery. Encapsulation Techniques: Encapsulating catalysts in materials such as polymers or silica can protect them from deactivation and improve their stability and reusability. Smart Delivery Systems: Incorporating responsive materials that can release catalysts under specific conditions (e.g., pH, temperature) can optimize reaction conditions and improve efficiency.
