Adaptive catalytic systems employ various mechanisms to achieve responsiveness. These can include: - Dynamic restructuring: Catalysts that change their morphology or active sites in response to reaction conditions. - Self-healing: Catalysts that can repair themselves when they become deactivated or poisoned. - Responsive materials: Catalysts made from materials that change properties, such as porosity or hydrophobicity, in response to external stimuli like temperature, pH, or the presence of specific chemicals.
