Catalyst lifespan is typically measured through a combination of laboratory tests and real-world applications. The primary metrics used include:
1. Turnover Number (TON): Indicates the number of times a catalytic site can facilitate the reaction before becoming inactive. 2. Turnover Frequency (TOF): Measures the number of catalytic cycles per unit time. 3. Deactivation Rate: The rate at which the catalyst loses its activity under specific conditions.
