Enhancing catalytic activity through metal doping can occur through several mechanisms:
1. Electronic Effects: Doping can change the electronic environment of the catalyst, altering its ability to donate or accept electrons during a reaction. 2. Structural Effects: Doped metals can modify the surface structure of the catalyst, creating new active sites or changing the geometry of existing ones. 3. Stabilization of Active Sites: The presence of dopant metals can stabilize active sites on the catalyst, preventing them from sintering or deactivating.
