Catalyst performance is typically evaluated using several parameters:
1. Activity: The rate at which a catalyst converts reactants to products. It is usually measured in terms of turnover frequency (TOF) or specific activity.
2. Selectivity: The ability of a catalyst to direct a reaction towards a specific product. High selectivity is crucial for minimizing by-products and improving process efficiency.
3. Stability: The durability of a catalyst over time. Stability testing involves repeated use of the catalyst and monitoring any loss in activity or selectivity.
4. Conversion: The percentage of reactants converted to products in a given reaction. High conversion rates are desirable for efficient catalytic processes.
