Regarding the catalyst aid
Thread Content
Based on their mechanism of action, catalysts can generally be divided into structural and electronic types. The selection and study of catalysts are very important issues in the field of catalysis. I wonder who can talk about the applications in this area

Structural additives: By acting on the structure of the carrier and active components, they primarily enhance the dispersion and stability of the active components； Electronic additives: Enhance the selectivity of the catalyst by altering its electronic structure. For example, in iron catalysts used for ammonia synthesis, adding a small amount of Al2O3 improves their activity and **extends their lifespan; Al2O3 acts as a structural additive. Adding K2O increases the electron density of Fe atoms, thereby enhancing their activity; hence, K2O is an electron-type catalyst.
