Bulk metal surfaces work by providing a platform for the adsorption of reactant molecules. The process typically involves the following steps: 1. Adsorption: Reactant molecules adsorb onto the metal surface. 2. Reaction: Adsorbed molecules interact with each other or with the metal atoms to form intermediate species. 3. Desorption: The final product molecules desorb from the surface, leaving the catalyst surface available for another cycle.
