During final approval, a series of rigorous tests are conducted to ensure the catalyst's reliability:
1. Activity Tests: These tests measure the catalyst's ability to accelerate the target reaction. 2. Selectivity Tests: These determine the catalyst's ability to produce the desired product without forming significant amounts of by-products. 3. Stability Tests: These assess how the catalyst performs over time and under stress conditions such as high temperature and pressure. 4. Regulatory Compliance Tests: These ensure the catalyst meets all legal and environmental regulations.
