How Do Bimetallic and Multimetallic Catalysts Work?
The working mechanism of bimetallic and multimetallic catalysts is often more complex than that of monometallic catalysts. The enhanced performance can be attributed to several factors:
Electronic Effects: The presence of a second metal can alter the electronic structure of the primary metal, affecting the adsorption and activation of reactants. Geometric Effects: The arrangement of the metal atoms can create unique active sites that are more effective for specific reactions. Ensemble Effects: The combination of different metals can create new types of active sites that are not present in the individual metals.
