What Challenges Exist in Studying Active Ingredients?
Several challenges can complicate the study of active ingredients in catalysis:
Complexity of Real Catalysts: Industrial catalysts often consist of multiple components and phases, making it difficult to isolate and study individual active sites. Dynamic Nature: Active sites can undergo changes during the reaction, such as restructuring or oxidation state variations, complicating their characterization. Scale of Observation: Techniques that provide atomic-level resolution are often limited to small sample sizes, which may not represent the behavior of the catalyst under real operating conditions.
