Once a catalyst is designed, it must be rigorously tested to ensure it meets the desired criteria:
1. Turnover Frequency (TOF): Measures the number of reactions catalyzed per active site per unit time. 2. Turnover Number (TON): Indicates the total number of reactions a single active site can catalyze before deactivation. 3. Selectivity: Assesses the proportion of desired product formed compared to undesired by-products. 4. Lifetime Testing: Long-term tests to ensure the catalyst remains active and stable over extended periods.
In conclusion, catalyst design is a complex yet fascinating field that combines theory, experimentation, and technology to develop materials that drive efficient and selective chemical reactions. By considering factors such as active sites, supports, morphology, promoters/inhibitors, and reaction conditions, researchers can create catalysts that meet specific industrial needs. Advances in computational methods and high-throughput experimentation continue to push the boundaries of what is possible in catalyst design.
