The synergy between Pt and Sn can be attributed to several factors:
Electronic Effects: Tin modifies the electronic properties of platinum, leading to changes in the adsorption and activation of reactants. Structural Effects: The presence of tin can alter the surface structure of platinum, providing more active sites for catalysis. Resistance to Deactivation: Tin helps in reducing coke formation and sintering, thereby enhancing the durability of the catalyst.
