Catalyst longevity is affected by several factors:
Sintering: High temperatures can cause catalyst particles to aggregate, reducing surface area and activity. Coking: The formation of carbon deposits can block active sites and deactivate the catalyst. Leaching: Loss of active components due to dissolution in the reaction medium. Structural Changes: Physical changes in the catalyst structure over time can diminish performance.
Addressing these challenges involves developing more robust catalysts and implementing regeneration techniques.
