Catalysis efficiency can be quantified using several metrics, including:
1. Turnover Frequency (TOF): This measures the number of catalytic cycles a catalyst can perform per unit time. 2. Turnover Number (TON): This represents the total number of substrate molecules a single catalyst molecule can convert before becoming inactive. 3. Selectivity: This indicates the catalyst's ability to favor the formation of a particular product over others. 4. Catalyst Lifetime: This refers to the duration over which a catalyst remains active and effective.
