How Do Electronic Properties Influence Catalytic Activity?
Electronic properties influence catalytic activity in several ways:
Adsorption Energy: The strength with which reactants and intermediates bind to the catalyst surface is crucial. This binding energy is influenced by the d-band center of the catalyst material. Charge Transfer: During a reaction, electrons may transfer between the reactants and the catalyst. The ease of this transfer is determined by the electronic properties of the catalyst, especially its work function. Stability of Intermediates: Intermediates must be stabilized on the catalyst surface for the reaction to proceed efficiently. The electronic structure affects how these intermediates are stabilized.
