Several mechanisms are frequently encountered in catalysis. These include:
Adsorption: Reactants are adsorbed onto the surface of the catalyst. Oxidative Addition: A bond in a reactant molecule is broken and the fragments are added to the catalyst. Reductive Elimination: The opposite of oxidative addition, this step involves the release of a product from the catalyst. Migration: Atoms or groups move from one site on the catalyst to another. Desorption: The final product is released from the catalyst surface.
