The mechanisms of hydrogen oxidation on catalytic surfaces involve several steps:
1. Adsorption: Hydrogen and oxygen molecules adsorb onto the catalyst surface. 2. Dissociation: These molecules dissociate into their atomic forms. 3. Surface Reaction: The hydrogen atoms react with oxygen atoms on the catalyst surface to form water. 4. Desorption: The water molecules desorb from the surface, leaving the catalyst ready for another cycle.
