How Do Dynamic Processes Affect Catalytic Activity?
Dynamic processes affect catalytic activity in several ways:
1. Adsorption and Desorption: The rates of adsorption and desorption of reactants and products on the catalyst surface determine the availability of active sites for the reaction. 2. Formation of Intermediates: The formation of reaction intermediates and their subsequent transformation into products can influence the overall reaction pathway and selectivity. 3. Catalyst Restructuring: Changes in the structure of the catalyst, such as sintering or phase transitions, can alter its activity and selectivity. 4. Surface Poisoning: The adsorption of unwanted species (poisons) can block active sites and reduce catalytic activity.
