What Are the Challenges of Thermal Annealing in Catalysis?
Despite its benefits, thermal annealing presents several challenges:
Optimal Temperature: Determining the optimal annealing temperature is critical. Too high a temperature can lead to excessive sintering, while too low a temperature might not achieve the desired structural improvements. Time Dependency: The duration of the annealing process also plays a significant role. Prolonged exposure might degrade the catalyst, whereas insufficient time might lead to incomplete transformation. Atmosphere Control: The environment in which annealing takes place (e.g., oxidizing, reducing, or inert atmosphere) can significantly affect the outcome. Precise control is necessary to achieve the desired modifications.
