Several key criteria must be evaluated during final approval:
1. Performance Metrics: The catalyst must demonstrate high activity, selectivity, and yield in the target reaction. 2. Durability: The catalyst should maintain its performance over extended periods and under varying operational conditions. 3. Scalability: The production and use of the catalyst must be feasible on a commercial scale. 4. Safety and Environmental Impact: The catalyst should be non-toxic, environmentally benign, and compliant with regulatory standards.
