What Role Do Spin States Play in Heterogeneous Catalysis?
In heterogeneous catalysis, the catalyst is in a different phase than the reactants. The surface properties of the catalyst, including its spin states, are crucial for catalytic performance. For example, on the surface of metallic catalysts, spin states can affect the bonding and activation of reactant molecules. Surface defects, which often have unpaired electrons, can also play a significant role in determining the catalytic activity and selectivity.
